President-elect Donald Trump’s top nominees are about to go under the Senate spotlight.

Hearings kick off on Tuesday, and while some of Trump’s most controversial picks appear to be on track for confirmation, others remain short of the support they need, according to conversations with a half-dozen GOP senators and aides.

This week’s public questioning could be decisive: “Right now, I think it looks like smooth sailing, but sometimes unexpected things happen,” Sen. John Cornyn (R-Texas) said.

With a 53-seat majority and incoming Vice President JD Vance available to break ties, the nominees could be in trouble if they lose support from more than three GOP senators. Several Republicans, whose comments are being closely watched by their colleagues, have been careful to stay publicly neutral on some.

But Republicans are also under fierce public pressure to move quickly toward confirmations, with Trump prepared to lash out publicly at any GOP lawmaker who waffles and some allies threatening potential primary challenges.

With that in mind, here’s a checkup on 18 of Trump’s most prominent nominees:

Pete Hegseth, Secretary of Defense

Tuesday, Jan. 14, 9:30 a.m., Senate Armed Services Committee

We might have had to make a “death watch” category a month ago, when Hegseth was swamped with allegations of sexual assault and alcohol abuse. But he has managed to resuscitate his chances at confirmation, denying any wrongdoing and riding a MAGA pressure campaign back into contention. And this week’s hearing in the Armed Services Committee could make or break whether he ultimately gets confirmed. The public grilling is guaranteed to revive many of the ugly headlines seen after Hegseth was nominated, but Trump has stood by him and his allies have made clear they will go after GOP senators who go wobbly. Senate Majority Leader John Thune told Fox News’ Laura Ingraham last week that Hegseth “has a path” to confirmation — still far from a guarantee.

Robert F. Kennedy Jr., Secretary of Health and Human Services

Date TBA, Senate Finance and HELP Committees

Trump’s most endangered pick is the former Democrat with controversial views about, well, just about everything. Senate HELP Chair Bill Cassidy (R-La.) gave a less-than-enthusiastic readout of his recent meeting with Kennedy last week, saying that they had a “frank” conversation but declining to say if he would support Trump’s pick. His skeptical stance on vaccinations has garnered skepticism, and in some cases criticism, from Cassidy, as well as Sens. Susan Collins (R-Maine), Lisa Murkowski (R-Alaska) and Mitch McConnell (R-Ky.). Those four senators alone would be enough to sink Kennedy’s nomination on the floor; Collins and Murkowski also sit on HELP with Cassidy. Also problematic: his previous comments supporting abortion, which have irked anti-abortion groups. One key question: Can Kennedy win over any Democrats?

Tulsi Gabbard, Director of National Intelligence

DATE TBA, Senate Intelligence Committee

Early predictions were that Gabbard, an outspoken critic of the U.S. national security establishment, would have trouble gaining confirmation to the nation’s top intelligence role. But recently GOP senators have spoken positively about their private meetings with her, moving her forthcoming nomination out of DOA territory. That doesn’t mean she is safe: Republicans privately warn that Gabbard’s fate will likely be decided by her hearing before the Senate Intelligence Committee, which will include a closed-door session. And Gabbard’s chances might not be entirely under her control: “Her chances decrease as Hegseth’s improve,” said a person familiar with committee discussions about her nomination. “Republicans are concerned about Gabbard but don’t want to torpedo too many of Trump’s nominees.”

Kash Patel, FBI Director

DATE TBA, Senate Judiciary Committee

Trump’s pick of Patel to lead the FBI — effectively ousting Director Chris Wray before the end of his 10-year term — sent shockwaves through Washington, including in the Capitol where some Senate Republicans were hoping he would pick former Rep. Mike Rogers (R-Mich.). But since then Patel has managed to assuage his GOP skeptics, or at least keep them on the fence, after a series of one-on-one meetings. Other top Republicans, including members of leadership, have predicted that he will be confirmed or downplayed concerns that he would use the FBI to carry out a vendetta against Trump’s political enemies. Expect Patel to face questions about that very topic during his Senate Judiciary Committee hearing.

Pam Bondi, Attorney General

Wednesday, Jan. 15, 9:30 a.m., Senate Judiciary Committee

A former Florida attorney general, Bondi’s credentials have resonated far better with Senate Republicans than Trump’s original pick, former Rep. Matt Gaetz (R-Fla.). Picked for the gig just hours after Gaetz dropped out, she has won rave reviews from the Senate GOP ever since. That makes her chances of confirmation seem particularly strong. But it’s unlikely Bondi picks up much Democratic support, if any. Sen. Dick Durbin (D-Ill.), the top Judiciary Democrat, met with Bondi earlier this month, but came out with a scathing statement that doubted her suitability for the job. Bondi has been closely aligned with Trump for years and served as his personal attorney following his loss in the 2020 election. That’s led to concerns among Democrats on whether Bondi would separate her role as attorney general from her fealty to the president.

Kristi Noem, Homeland Security Secretary

Wednesday, Jan. 15, 9 a.m., Senate Homeland Security and Governmental Affairs Committee

In Noem, Trump is seeking to put a fierce supporter in charge of carrying out his sweeping plan to crack down on immigration. Noem found herself at the center of a days-long controversy last year over an excerpt from her autobiography in which she wrote about fatally shooting her dog Cricket. And Democrats have also raised red flags over Trump’s border and immigration plans, which were at the center of his battles with his congress during his first administration. Yet Noem’s nomination has largely flown under the radar on Capitol Hill as she’s quietly met with senators ahead of her hearing.

Doug Burgum, Interior Secretary

Thursday, Jan. 16, 10 A.M., Senate Energy and Natural Resources Committee

The former North Dakota governor is expected to easily be confirmed, potentially even with bipartisan support. Yet his nomination became the center of a partisan committee clash last week that could inject tensions into his hearing this week. New Mexico Sen. Martin Heinrich, the Energy panel’s top Democrat, accused Chair Mike Lee (R-Utah) of scheduling a hearing before the committee had received all of its paperwork; Republicans said they expected to have the documentation in time for the hearing. Expect Democrats to grill Burgum on Trump’s vows to undo Biden clean energy policies.

Lori Chavez-DeRemer, Labor Secretary

Date TBA, Senate HELP Committee

Chavez-DeRemer might be the closest Trump gets to reaching across the aisle: Though she’s a former Republican House member, she was also a co-sponsor of the Protecting the Right to Organize Act last Congress, organized labor’s top legislative priority. Teamsters President Sean O’Brien is among those supporting Chavez-DeRemer’s nomination. But while there are a few semi-labor-friendly Senate Republicans, they are rare. Most are firmly opposed to expanding union rights and are looking for Trump’s Labor secretary to roll back Biden administration regulations. Still, there’s little sign they’ll put up roadblocks here, even with some in the business community fidgeting over her nomination. She might even pick up a few Democrats along the way.

Sean Duffy, Transportation Secretary

Wednesday, Jan. 15, 10 a.m., Senate Commerce, Science and Transportation Committee

Duffy — a former House Republican from Wisconsin, Fox Business personality and “Real World” alumnus — is expected to be easily confirmed. Some Democrats have already indicated that they will support him, absent a major misstep. Duffy beat out two other members of Congress who were also viewed as in the running: Rep. Sam Graves (R-Mo.) and former Rep. Garret Graves (R-La.). He’ll take over the department that is dealing with a spate of recent near-collisions on runways plus aging aviation equipment.

Marco Rubio, Secretary of State

Wednesday, Jan. 15, 10 a.m., Senate Foreign Relations Committee

The Florida senator is arguably in the best shape for confirmation of any of Trump’s nominees. Senators already know him. As the former ranking member on the Senate Intelligence Committee and a longtime Foreign Relations member, his international affairs chops are hard to assail. And he has solid relationships with members on both sides of the aisle, with a number of Senate Democrats already pledging to support his nomination on the floor. If Democrats give Trump any Day One confirmations, expect Rubio to be among them.

Chris Wright, Energy Secretary

Wednesday, Jan. 15, 10 a.m., Senate Energy and Natural Resources Committee

Wright, a longtime oil industry CEO with skeptical views on climate change, will be hard to swallow for Democrats but appears perfectly fine to Republicans. Wright’s policy preferences are well in line with the president-elect’s: He’s been critical of efforts to curb greenhouse gas emissions and transition to cleaner energy sources. Members of the Senate GOP have lauded the pick, including members of leadership, pointing to a speedy confirmation.

Scott Bessent, Treasury Secretary

Thursday, Jan. 16, 10:30 a.m., Senate Finance Committee

Bessent has been coasting through his meetings with lawmakers and staff — teeing up a swift path to confirmation for the longtime hedge fund manager. Republicans have quickly coalesced behind him, while moderate Democrats haven’t totally ruled out supporting him on the floor. Bessent has been a Wall Street ally to Trump and joined the president-elect on the campaign trail at multiple points this cycle to talk economic policy. Bessent worked closely in the past with Democratic megadonor George Soros, but that doesn’t appear to be weighing him down among conservatives. Senate Finance Chair Mike Crapo (R-Idaho) has committed to moving Bessent’s nomination quickly.

Elise Stefanik, United Nations Ambassador

Thursday, Jan. 16, 10 a.m., Senate Foreign Relations Committee

The New York congresswoman, once among Trump’s most ardent allies on Capitol Hill, appears to be on a glide path to confirmation. Though Stefanik frequently tangled with Democrats during her time in Congress, New Hampshire Sen. Jeanne Shaheen, the top Democrat on the Foreign Relations Committee, offered a politely worded statement after their meeting. Republicans view Stefanik as a pick who could potentially be confirmed on Jan. 20 — though that would likely require buy-in from every Democrat to speed up the schedule.

Scott Turner, Housing and Urban Development Secretary

Thursday, Jan. 16, 10 a.m., Senate Banking, Housing and Urban Affairs Committee

Turner is a relative cipher among Trump’s slate of Cabinet nominees: He previously headed up the White House Opportunity and Revitalization Council during Trump’s first term, working with so-called “opportunity zone” tax incentives. But that post did not require Senate confirmation for the former NFL player, who now works as a motivational speaker and as “chief visionary officer” for a Texas-based housing developer. He’ll face tough Democratic questions over Trump’s plans to Biden initiatives at HUD, but expect little GOP skepticism.

Doug Collins, Veterans Affairs Secretary

Date TBA, Senate Veterans Affairs Committee

Trump’s pick of the former House Republican from Georgia would put a long-time loyalist — one who helped lead the opposition to his 2019 impeachment in the House Judiciary Committee — in charge of the sprawling, politically sensitive VA. While Collins was viewed by many as a surprise pick, his nomination has not generated major partisan fireworks, and he’s expected to easily be confirmed. Still, expect Collins to field questions from Democrats on whether he has plans to further privatize the department.

Howard Lutnick, Commerce Secretary

Date TBA, Senate Commerce, Science and Transportation Committee

Lutnick parlayed his role as transition co-chair into a Cabinet nomination, and Trump has already tasked the billionaire megadonor with carrying out some commerce-related talks — including meeting with Canadian representatives to discuss upcoming trade negotiations, with Trump’s tariff threats weighing heavily on the North American alliance. There’s been little sign of pushback from Republicans, and he’s picked up a few nice words, at least, from Senate Minority Leader Chuck Schumer, who met with the nominee last month. Schumer said in a statement that he’s known the fellow New Yorker for years and that “he’s an intelligent and capable man.”

Linda McMahon, Education Secretary

Date TBA, Senate HELP Committee

McMahon has been making rounds with committee staff and members since late last year. Her credentials for the job are more about her status as a longtime Trump loyalist and current co-chair of his transition team than her life experience, though she did serve for a year on the Connecticut Board of Education. That said, McMahon is likely to easily slide toward confirmation. The former professional wrestling executive previously served as head of the Small Business Administration during Trump’s first term, meaning most Republican senators are comfortable with her, even if her views on education are somewhat opaque.

Brooke Rollins, Agriculture Secretary

Date TBA, Senate Agriculture Committee

Rollins is expected to easily gain confirmation, with support from several Democrats likely. The bipartisan backing for Rollins had made her a potential Day One confirmation, which requires buy-in from all 100 senators to move quickly, but the schedule for moving her forthcoming nomination has hit paperwork delays. Her hearing hasn’t yet been scheduled, and Republicans say they expect Chair John Boozman (R-Ark.) to give seven days’ notice before holding one.
