WEST PALM BEACH, Fla. — Donald Trump chose Rep. Matt Gaetz of Florida to serve as his attorney general on Wednesday, bypassing more experienced options in favor of a loyalist who has built a national reputation as a disruptor and whom Trump has tasked with dramatically overhauling the Justice Department.

Trump also announced that he had tapped Sen. Marco Rubio of Florida as his nominee for secretary of state. And he selected Tulsi Gabbard, a former Democratic member of Congress and presidential candidate, to serve as his director of national intelligence.

The choices continued a pattern of Trump stocking his Cabinet with loyalists he believes he can trust to execute his agenda rather than longtime officials with experience in their fields. Gaetz’s selection, in particular, was seen as a shock. The Florida lawmaker was not among the more established attorneys who had been mentioned as contenders for the job, and even his colleagues in Congress appeared stunned by the news.

“Everybody was saying, ‘Oh my God,’ ” said Republican Rep. Mike Simpson of Idaho. “That was about as big a surprise as I’ve had in a long time.”

Trump announced the decision in a post in his Truth Social network, saying Gaetz would “root out the systemic corruption at DOJ, and return the Department to its true mission of fighting Crime, and upholding our Democracy and Constitution.”

Gaetz represents much of the Florida Panhandle and became a conservative star when he joined Congress, appearing as a frequent staunch defender of Trump on cable news.

He irked fellow GOP members in early 2023 when he filed the resolution that successfully ousted former House Speaker Kevin McCarthy. McCarthy then helped fund a primary challenge to Gaetz that included commercials alleging that he paid for sex with a 17-year-old, an allegation currently investigated by the House Ethics Committee. Gaetz has denied any wrongdoing and the Justice Department ended its own sex trafficking investigation without bringing charges against him.

Inside a private meeting of House Republicans, GOP lawmakers first thought the news was a joke before realizing Trump had indeed named Gaetz to serve as the nation’s chief law officer.

GOP Rep. Max Miller told reporters the shock in the room was more a reflection of members’ happiness that the Florida Republican will no longer be a member of the chamber after years of instigating interparty battles.

Even Trump’s allies in the Senate were keeping their distance.

“We’ll see,” said Sen. Ron Johnson of Wisconsin when asked whether he would vote to confirm the congressman.

Sen. John Cornyn, a Texas Republican, suggested that the Senate would look closely into Gaetz, including the House Ethics Committee investigation.

“I’m sure it will make for a popcorn-eating confirmation hearing,” said GOP Sen. Thom Tillis of North Carolina.

Sen. Richard Blumenthal, D-Conn., who serves on the committee that will take up the Gaetz nomination, said it would be “the first test of whether Republicans are willing to stand up to Donald Trump and go with conscience and conviction as opposed to just politics.”

The announcement came shortly after Trump confirmed that he had picked Rubio, a conservative lawmaker, as the nation’s top diplomat. A onetime critic who evolved into one of the president-elect’s fiercest defenders, Rubio, who will become the first Latino in the job, is a noted hawk on China, Cuba and Iran, and was a finalist to be Trump’s running mate this summer.

On Capitol Hill, Rubio is the vice chairman of the Senate Intelligence Committee and a member of the Senate Foreign Relations Committee. He has pushed for taking a harder line against China and has targeted social media app TikTok because its parent company is Chinese. He and other lawmakers contend that Beijing could demand access to the data of users whenever it wants.

“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,” Trump said of Rubio in a statement.

Trump made the announcement while flying back back to Florida from Washington after meeting with President Joe Biden.

The president-elect had been expected to pick Rubio for the post, but had also faced pressure from allies of Ric Grenell, who served as acting director of national intelligence during Trump’s first administration.

Grenell responded to the news on on X, writing, “Congratulations, Senator. You will be great for America!”

The selection is the culmination of a long, complicated history between Trump and Rubio. During their tense competition for the GOP presidential nomination in 2016, Rubio was especially blunt in his criticism of Trump. He tried to match Trump’s often-crude attacks by joking about the size of Trump’s hands in a reference to his manhood. Trump responded by branding Rubio as “little Marco,” a nickname that stuck.
