Donald Trump will begin his second term as president the same way he began his first—with Republicans controlling both the House and Senate.

The GOP scored its 218th House-race victory—enough to clinch a majority of the chamber’s 435 seats—today when CNN and NBC News declared Republicans the winner of two close elections in Arizona. How many more seats the Republicans will win depends on the outcome of a few contests, in California and elsewhere, where ballots are still being counted. But the GOP’s final margin is likely to be similar to the four-seat advantage it held for most of the past two years, when internal division and leadership battles prevented the party from accomplishing much of anything.

Such a slim majority means that the legislation most prized on the right and feared by the left—a national abortion ban, dramatic cuts to federal spending, the repeal of Barack Obama’s Affordable Care Act and Joe Biden’s largest domestic-policy achievements—is unlikely to pass Congress. “I don’t think they’re even going to try on any of those things,” Brendan Buck, who served as a top aide to former Speaker Paul Ryan during Trump’s first term, told me.

[Daniel Block: The Democrats’ Senate nightmare is only beginning]

Trump’s biggest opportunity for a legacy-defining law may be extending his 2017 tax cuts, which are due to expire next year and won’t need to overcome a Senate filibuster to pass. He could also find bipartisan support for new immigration restrictions, including funding for his promised southern wall, after an election in which voters rewarded candidates with a more hawkish stance on the border.

In 2017, Trump took office with a 51–49 Republican majority in the Senate and a slightly wider advantage in the House—both ultimately too narrow for him to fulfill his core campaign promise of axing the ACA. Next year, the dynamic will be reversed, and he’ll have a bit more of a cushion in the Senate. Republicans gained four seats to recapture the majority from Democrats; they now hold a 53–47 advantage, which should be enough to confirm Trump’s Cabinet picks and judicial nominees. The impact on the Supreme Court could be profound: Trump named three of its nine members during his first term, and should Justices Clarence Thomas and Samuel Alito, who are both in their 70s, retire in the next two years, he would be responsible for nominating a majority of the Court.

Yet on legislation, Republicans will be constrained by both the Senate’s rules and the party’s thin margin in the House. Republicans have said they won’t try to curtail the Senate’s 60-vote threshold for circumventing a filibuster. “The filibuster will stand,” the outgoing Senate minority leader, Mitch McConnell, declared on the day after the election. But he’ll be only a rank-and-file member in the next Congress. McConnell’s newly elected successor as party leader, Senator John Thune of South Dakota, reiterated his commitment to the legislative filibuster after winning a secret-ballot election for the role.

How many votes are needed to pass bills in the Senate won’t mean much if Trump can’t get legislation through the House, and that could be a far more difficult proposition. The two speakers during the current Congress, Kevin McCarthy and Mike Johnson, each had to rely on Democrats to get major bills passed, because the GOP’s majority proved too thin to govern. With Trump’s backing, Johnson should have the votes to stay on as speaker when the new Congress convenes in January. (When Trump addressed House Republicans today in Washington, the speaker hailed him as “the comeback king” and, NBC News reported, the president-elect assured Johnson he would back him “all the way.”)

But the Republican edge could be even narrower next year if Democrats win a few more of the final uncalled races. Trump’s selection of Representative Elise Stefanik of New York to serve as United Nations ambassador and Representative Mike Waltz of Florida to serve as national security adviser could deprive Republicans of two additional seats for several months until voters elect their replacements. (Senator Marco Rubio’s expected nomination as secretary of state won’t cost the GOP his Florida seat, because Governor Ron DeSantis can appoint an immediate replacement.)

Still, the GOP has reason to hope for a fruitful session. During Biden’s first two years in office, House Democrats demonstrated that even a small majority could produce major legislation. They passed most of Biden’s agenda—though the Senate blocked or watered down some of it—despite having few votes to spare. And Trump exerts a much tighter grip on his party than Biden did on congressional Democrats. Unlike during Trump’s first term, few if any Republicans hostile to his agenda remain in the House. His decisive victory last week, which includes a likely popular-vote win, should also help ensure greater Republican unity.

“I think we will have a much easier time in terms of getting major things passed,” predicts Representative Mike Lawler of New York, whose victory in one of the nation’s most closely watched races helped Republicans keep their majority. “The country was very clear in the direction it wants Congress and the presidency to go.”

Trump might even hold sway over a few Democrats on some issues. Because Trump improved his standing almost everywhere last week, the House in January will include many Democrats who represent districts that he carried. Two House Democrats who outran their party by wide margins, Representatives Jared Golden of Maine and Marie Gluesenkamp Perez of Washington State, refused to endorse Kamala Harris, while several candidates who more fully embraced the party’s national message underperformed. Nearly all Democratic candidates in close races echoed Trump’s calls for more aggressive action to limit border crossings, which could yield the new president additional support in Congress for restrictive immigration legislation.

[Mike Pesca: The HR-ification of the Democratic Party]

Like most House Republicans, Lawler endorsed Trump, but he ran on a record of bipartisanship and told me he’d be unafraid to defy the president when he disagreed. As a potential swing vote in a narrow majority, he could have more influence over the next two years. Lawler told me Monday that the GOP should heed the voters’ call to focus on issues such as the economy, border security, tax cuts, and energy production. Pursuing a national abortion ban, he said, would be “a mistake.” And Lawler serves as a reminder that enacting legislation even in an area where Republicans are relatively unified, like tax cuts, could be difficult: He reiterated his vow to oppose any proposal that does not restore a costly deduction for residents of high-tax states such as New York and California—a change that Trump supports but many other Republicans do not.

Trump showed little patience for the hard work of wrangling votes during his first term. Now he’s testing his might on Capitol Hill—and displaying his disdain for Congress’s authority—even before he takes office. Though he didn’t endorse a candidate to succeed McConnell, he urged all of the contenders to allow him to circumvent the Senate by making key appointments when Congress is in recess. After he won, Thune wouldn’t say whether he’d agree. Trump apparently wants the ability to install nominees—Robert F. Kennedy Jr. as secretary of health and human services?—who can’t win confirmation by the Senate.

“The Trump world does not give a damn about normal processes and procedures and traditions and principles of the prerogatives of certain chambers,” Buck, the former GOP aide, said. “They just want to do stuff.” The fight could be instructive, an early indication that no matter how much deference the new Republican majority is prepared to give Trump, he’ll surely still want more.

A note from Tom:

As we were about to publish this newsletter, Donald Trump announced that he has asked the Fox News personality Pete Hegseth, a military veteran who has no experience in leading large organizations and no serious background as a senior leader in national-security affairs, to be his secretary of defense. This is exactly the kind of unqualified nomination that I was warning could be looming after this first group of nominees were announced—and it explains why Trump is determined to bypass the U.S. Senate to get some of his nominees confirmed. I will have more to say about Hegseth soon.

So far, the new Trump administration has a chief of staff, a “border czar,” and a national security adviser; all three are White House positions controlled by the president. Donald Trump has also reportedly named six people to senior positions that require Senate confirmation: secretary of state, United Nations ambassador, secretary of homeland security, secretary of defense, CIA director, and administrator of the Environmental Protection Agency. (He has also chosen an ambassador to Israel.) His first picks are neither very surprising nor very impressive, but this is only the beginning.

His co–campaign manager Susie Wiles will make White House history by becoming the first female chief of staff. People around Trump seem relieved at this appointment, but she’ll likely be saddled with Stephen Miller as a deputy, which could get interesting because Miller apparently has a tendency to get out of his lane. (According to a book by the New York Times reporter Michael Bender, Miller attended a tense meeting that included Trump, Attorney General Bill Barr, and General Mark Milley, the chairman of the Joint Chiefs of Staff, during the Black Lives Matter protests in 2020. As the nation’s leaders debated what to do, Miller interjected and said that America’s major cities had been turned into war zones. General Milley, Bender writes, turned to Miller, pointed at him, and said: “Shut the fuck up, Stephen.”)

The rest of the appointments are unsurprising, given the limited pool of Republicans willing to serve in another Trump administration. (Some Trump loyalists such as Senator Tom Cotton have reportedly declined a role in the administration, likely protecting their future for the 2028 GOP race to succeed Trump.) Marco Rubio, who sits on the Foreign Relations and Intelligence Committees in the Senate, was a reasonable choice among the Trump coterie to become America’s top diplomat as secretary of state.

Likewise, Representative Mike Waltz of Florida is a reasonable choice for national security adviser—but again, that’s in the context of the now-smaller universe of national-security conservatives in politics or academia willing to work for Trump at this point. He is a veteran, and like Rubio, he has served on relevant committees in Congress, including Armed Services, Foreign Affairs, and the House Permanent Select Committee on Intelligence. Waltz may be a credible voice on national security, but he was also a 2020 election denier. He pledged to oppose certifying Joe Biden’s 2020 win and signed on to an amicus brief supporting a Texas lawsuit to overturn the election. He changed his mind—but only after the events of January 6.

Representative Elise Stefanik of New York, meanwhile, was bound to be rewarded for her loyalty. Although Vice President–elect J. D. Vance took the gold in the race to replace the disowned Mike Pence, Stefanik was a comer even by the standards of the sycophantic circle around Trump, and so she’ll head to the United Nations, a low-priority post for Trump and a GOP that has little use for the institution. A former member of Congress from New York, Lee Zeldin (who was defeated in the 2022 New York governor’s race) will head up the EPA, another institution hated by MAGA Republicans, thus making Zeldin’s weak—or strong, depending on your view—legislative record on environmental issues a good fit for this administration.

This afternoon, Trump announced that John Ratcliffe will serve as CIA director. Ratcliffe previously served as director of national intelligence and will now be in a post that is functionally subordinate to his old job. Ratcliffe is a reliable partisan but an unreliable intelligence chief. The most baffling move Trump has made so far is the appointment of South Dakota Governor Kristi Noem to lead the Department of Homeland Security. Noem served four terms in Congress and is in her second as governor. She has very little relevant experience, especially as a government executive. (South Dakota might be a big place, but it’s a small state; DHS has more than 260,000 employees, making it a bit more than a quarter the size of the entire population of Noem’s home state.) DHS is a giant glob of a department—one I have long argued should never have existed in the first place and should be abolished—that has seeped across the jurisdictional lines of multiple institutions and, unlike some other Cabinet posts, requires someone with serious leadership chops.

DHS will also be central to some of Trump’s most abominable plans regarding undocumented immigrants—and, potentially, against others the president-elect views as “enemies from within.” (The “border czar” Trump has named, Tom Homan, once falsely implied that some California wildfires were worsened by an undocumented immigrant.) In that light, Noem is perfect: She is inexperienced but loyal, a political lightweight with no independent base of support or particularly long experience in Washington, and she can be counted on to do what she’s told. She will be no John Kelly or Kirstjen Nielsen, her confirmed predecessors at DHS, both of whom were on occasion willing to speak up, even if ineffectively.

This first passel of nominees should gain Senate confirmation easily, especially Rubio. (Sitting members of the chamber usually have an easier time, as do people who have close associations with the Senate.) And given Trump’s history and proclivity for mercurial and humiliating firings, few of them are likely to be very long in their post, and are probably better than the people who will later replace them.

But that in itself raises a troubling question. If Trump intends to nominate these kinds of fellow Republicans, why is he insistent that the new Senate allow him to make recess appointments?

For those of you who do not follow the arcana of American government, Article II of the Constitution includes a provision by which the president can make appointments on his own if the Senate is in recess and therefore unable to meet. The Founders didn’t think this was a controversial provision; sometimes, presidents need to keep the government running (by choosing, say, an ambassador) even when the Senate might not be around—a real problem in the days when convening the Senate could take weeks of travel. Such appointments last until the end of the next legislative session.

For obvious reasons, the Senate itself was never a big fan of a device—one that presidents routinely used—that circumvents constitutional authority to confirm executive appointments, especially once the practice got out of hand. (Bill Clinton made 139 recess appointments, George W. Bush made 171, and Barack Obama made 32.) The Senate’s response was basically to be wilier about not declaring itself in recess even when there’s no one around, and when President Obama tried to push through some of these appointments in 2012, the Supreme Court sided with the Senate.

Now Trump wants to bring back the practice. The obvious inference to draw here is that after some fairly uncontroversial nominations, he intends to nominate people who couldn’t be confirmed even in a supine and obedient Republican Senate. Perhaps this is too clever, but I am concerned that this first pass is a head fake, in which Trump nominates people he knows are controversial (such as Zeldin) but who are still confirmable, and then sends far worse candidates forward for even more important posts. Kash Patel—a man who is dangerous precisely because his only interest is serving Trump, as my colleague Elaina Plott Calabro has reported—keeps bubbling up for various intelligence posts.

“Ambassador Elise Stefanik” and “EPA Administrator Lee Zeldin” might not be great ideas, but they are not immediate threats to U.S. national security or American democracy. “CIA Director John Ratcliffe,” by contrast, is cause for serious concern. If Trump is serious about his authoritarian plans—the ones he announced at every campaign stop—then he’ll need the rest of the intelligence community, the Justice Department, and the Defense Department all under firm control.

Those are the next nominations to watch.

The judge in Trump’s hush-money criminal case delayed his decision on whether Trump’s conviction on 34 felonies should be overturned after his reelection. A federal judge temporarily blocked a new Louisiana law that would have required the display of the Ten Commandments in all public classrooms, calling the legislation “unconstitutional on its face.” Louisiana’s attorney general said that she will appeal the ruling. The Archbishop of Canterbury announced his resignation. An independent review found that he failed to sufficiently report the late barrister John Smyth, who ran Christian summer camps and abused more than 100 boys and young men, according to the review.

AI Can Save Humanity—Or End It

By Henry A. Kissinger, Eric Schmidt and Craig Mundie

The world’s strongest nation might no longer be the one with the most Albert Einsteins and J. Robert Oppenheimers. Instead, the world’s strongest nations will be those that can bring AI to its fullest potential.

But with that potential comes tremendous danger. No existing innovation can come close to what AI might soon achieve: intelligence that is greater than that of any human on the planet. Might the last polymathic invention—namely computing, which amplified the power of the human mind in a way fundamentally different from any previous machine—be remembered for replacing its own inventors?
