Trump's picks include RFK Jr., Marco Rubio, Elon Musk, Matt Gaetz and more.
After a sweeping victory over Vice President Kamala Harris on Nov. 5, President-elect Donald Trump is now set to become just the second ever to serve nonconsecutive terms in office.
Trump has wasted no time in moving to assemble his team for a second term in the White House -- naming Susie Wiles as his chief of staff, Florida Rep. Mike Waltz as his national security adviser and Tom Homan as his "border czar," among other positions.
Inauguration Day is Jan. 20.
President-elect Donald Trump is naming cabinet members and adding other key positions to his administration.
These team members will have a direct impact on implementing Trump's policies in his second term.
MORE | Here's a look at the president-elect's other appointees so far.
Trump has officially announced Florida Sen. Marco Rubio as his nomination for secretary of state.
"Marco is a Highly Respected Leader, and a very powerful Voice for Freedom," Trump said in a statement. "He will be a strong Advocate for our Nation, a true friend to our Allies, and a fearless Warrior who will never back down to our adversaries."
The role must be confirmed by the Senate.
As Trump continues to round out his cabinet, the job of treasury secretary remains in flux, with the co-chair of Trump's transition team actively vying for the job, sources familiar with the matter told ABC News.
Howard Lutnick is looking to be tapped as treasury secretary, sources said, a move that comes as investor and hedge fund manager Scott Bessent is also a top contender for the role.
Bessent traveled to Mar-a-Lago as recently as Friday to meet with Trump about the job, the sources said.
Lutnick, on the other hand, spends hours with Trump nearly each day, presenting candidates for top roles in the administration. As such, the move by Lutnick to attempt to get a cabinet position for himself has frustrated some close to Trump.
Sources caution the job is still in flux and neither man could get the job -- with the potential for other candidates to emerge.
One potential dark horse for the job, one source told ABC News, is former Trump administration trade representative Robert Lighthizer, who Trump sees as an aggressive advocate for his tariff-heavy approach to international trade.
ABC News reports that the Republicans are projected to retain control of the U.S. House of Representatives.
Republicans are projected to control all three branches of government -- The U.S. House of Representatives, Senate and the White House.
Trump announced his senior staff on Wednesday, bringing back some of his well-known names from his first term and those who helped on his campaign.
Dan Scavino, one of Trump's long-time allies, was named assistant to the president and deputy chief of staff. Stephen Miller was named assistant to the president and deputy chief of staff, a move reported earlier this week.
James Blair, the Republican National Committee political director and campaign aide, has been named assistant to the president and deputy chief of staff for legislative, political and public affairs. Taylor Budowich will serve as assistant to the president and deputy chief of staff for communications and personnel. He was a senior member of several of Trump's PACs.
