Former President Donald Trump announced a comeback presidential campaign in November. But so far, most high-profile Republicans have yet to endorse him — or any other candidate.

As of Friday, February 17, five senators and over two dozen House members had announced they're backing Trump in 2024 or expressed support for his bid. Just one Republican governor has endorsed the former president.

Trump was the first major Republican to announce a 2024 candidacy, but a majority of his party hasn't rallied behind him. Most elected Republicans say they want to wait to see who runs, or that it's too early to make a decision.

Some are even contemplating, or have already launched, their own White House bids.

As president, Trump maintained an ironclad grip over the GOP. Even after his term — and an unprecedented assault on the US Capitol on January 6, 2021 by a crowd of his supporters — he's shown an ability to influence Republican primary voters and exact retribution upon his intraparty foes.

But after a disappointing midterms performance for the party — the GOP made only modest gains in the House, Democrats held the Senate, and many of Trump's preferred candidates performed poorly— some see the former president's power as waning.

Still, many of Trump's allies and longtime loyalists are sticking beside him.

Here are all of the prominent Republicans who have expressed support for Trump's 2024 campaign:

One governor

Henry McMaster — the South Carolina governor was announced as a member of Trump's campaign leadership team at a January 28 event in Columbia, where he declared that the country will "see a burst of freedom and prosperity unlike any we have ever seen before" if Trump is re-elected.

Five senators

Lindsey Graham — the long-serving South Carolina senator has formed a close relationship with Trump over the years, becoming one of his leading allies in Congress. "I know the downside of Trump, but let me tell you about the upside of Trump: there are no Trump policies without Trump," Graham told Fox News in January, touting Trump's achievements.

Markwayne Mullin — another Senate newcomer, Mullin of Oklahoma announced last week on Truth Social that he's "proud to endorse the strongest president of my lifetime, Donald J. Trump, for a second term in 2024."

Eric Schmitt — the newly elected senator told Politico last month he's backing the former president in 2024, who also endorsed Schmitt in Missouri's GOP primary last year.
