Among 12 prominent endorsements, which started with primary challenges to incumbent Republicans, four won election in Tuesday's voting, while two lost. Three remained uncalled and three lost their primaries.

Here's a look at Trump's record:

WINNERS

J.D. Vance

* Won U.S. Senate seat for Ohio vacated by retiring Republican Senator Rob Portman

The Trump-backed Vance is widely known as the author of best-seller "Hillbilly Elegy," which documented the descent of factory towns in states like Ohio into poverty and drug abuse. For the Senate contest, he shed his reputation as a Trump critic and styled himself as an angry populist in the Trump mold, winning the former leader's endorsement. In the midterm contest, he defeated Democrat Tim Ryan, currently a U.S. representative for Ohio.

Ted Budd

* Won U.S. Senate seat for North Carolina vacated by retiring Republican Senator Richard Burr

Budd narrowly defeated Democrat Cheri Beasley in the Senate contest. A rank-and-file member of the House of Representatives, Budd had little statewide name recognition before he sought the Republican nomination. Following Trump's endorsement, he surged in opinion polls and easily defeated former North Carolina Governor Pat McCrory in the May 17 primary.

Harriet Hageman

* Won Wyoming's at-large congressional district

Trump threw his backing behind Hageman, a lawyer, in September 2021, looking to punish incumbent U.S. Republican Representative Liz Cheney, who was stripped of her role as the No. 3 House Republican for voting to impeach the former president on a charge of inciting the Jan. 6, 2021, Capitol riot. Cheney, the daughter of former U.S. Vice President Dick Cheney, also served as the vice chair of the House committee investigating the Capitol attack. Hageman easily won the Nov. 8 contest to represent Wyoming, which is overwhelmingly Republican.

Russell Fry

* Won South Carolina's 7th congressional district, which is strongly Republican

Fry, a state representative, won Trump's endorsement after U.S. Representative Tom Rice joined Democrats and a handful of Republicans in voting to impeach the former president for inciting the deadly attack on the Capitol. Fry defeated Rice in the June 14 Republican primary, telling supporters afterward he would work hard to make Trump proud. On Nov. 8, he easily beat Democratic opponent Daryl Scott.

LOSERS

Mehmet Oz

* Lost race for U.S. Senate seat for Pennsylvania vacated by retiring Republican Senator Pat Toomey

Trump's endorsement of the celebrity doctor divided Republican leaders in Pennsylvania. Oz was defeated by Democratic Lieutenant Governor John Fetterman in a close race, after facing accusations of carpetbagging as a longtime New Jersey resident. Oz only narrowly beat former hedge fund executive David McCormick in the Republican Party's nomination contest.

John Gibbs

* Lost bid for Michigan's 3rd congressional district

Gibbs lost to Democrat Hillary Scholten in what had been expected to be a close contest. A former housing official under Trump with a history of inflammatory tweets, including references to baseless conspiracy theories about Democrats and Satanism, Gibbs had defeated U.S. Representative Peter Meijer, a fellow Republican, in the Aug. 2 primary after a Democratic Party group spent heavily on television ads touting Trump's endorsement. Meijer, one of the few Republicans who voted to impeach Trump last year, slammed the ads as a ploy to help his "far-right opponent" get on the ballot and make it easier for Democrats to win the moderate district in November.

TO BE DETERMINED

Herschel Walker

* Will face Democratic incumbent in a run-off for Georgia U.S. Senate seat

A retired football star who has never held elected office, Walker trailed Democratic Senator Raphael Warnock in Nov. 8 vote tallies. But because neither candidate won 50% of the vote, they will face off again in a Dec. 6 run-off. Trump-endorsed Walker's vulnerabilities include allegations of domestic abuse. A vocal anti-abortion advocate, Walker's campaign was rocked by reports that he paid for multiple former girlfriends to have abortions. He denied all allegations against him.

Kelly Tshibaka

* Seeks to defeat incumbent U.S. Republican Senator Lisa Murkowski of Alaska

Trump backed Tshibaka, a former Alaska state administration commissioner, to unseat Murkowski, one of seven Republican senators who voted to convict Trump in 2021 on impeachment charges. Both Murkowski and Tshibaka advanced from an August primary contest, under new state election rules which send four candidates to the general election regardless of their political parties. The winner is not yet known. Voters were asked to rank their candidates by preference, and Murkowski - a moderate who won re-election in 2010 as a write-in candidate after losing the Republican primary - could win if she garners more second-choice votes than Tshibaka. Vote counting is expected to last days or weeks.

Joe Kent

* Seeking Washington state's 3rd congressional district

Kent, a former special forces officer endorsed by Trump, was locked in a tight race with Democrat Marie Gluesenkamp Perez, a small business owner. Kent narrowly won the Aug. 2 Republican primary over incumbent U.S. Representative Jaime Herrera Beutler, who voted to impeach Trump last year. Kent has campaigned with far-right U.S. Representative Matt Gaetz of Florida and told Oregon Public Broadcasting he held a social media strategy call with white nationalist Nicholas Fuentes, though he said he disagreed with Fuentes' "ethno-nationalism."

LOSERS IN PRIMARIES

Loren Culp

* Lost to incumbent U.S. Republican Representative Dan Newhouse

Former small-town police chief Loren Culp won Trump's endorsement to take on Newhouse, who had stoked Trump's ire by voting to impeach him last year. But Newhouse advanced in the Aug. 2 Republican primary, with Culp blaming his loss on a crowded field of Republican candidates who were similarly pro-Trump. Newhouse easily won re-election on Tuesday.

David Perdue

* Went up against Georgia's incumbent Republican Governor Brian Kemp

Despite Trump's endorsement, former U.S. Senator David Perdue did not come close to upsetting Georgia's incumbent Republican Governor Brian Kemp in the party's nomination contest. Kemp, who had angered Trump by dismissing the former president's false statements about election fraud in the 2020 presidential contest, won his re-election bid against Democrat Stacey Abrams.

Katie Arrington

* Challenged Republican U.S. Representative Nancy Mace

Arrington, a former South Carolina state lawmaker, won Trump's endorsement after incumbent Mace publicly criticized Trump for his role in his supporters' assault on the U.S. Capitol. Mace, who voted against Trump's impeachment, defeated Arrington in the Republican nomination contest in June and on Tuesday easily defeated Democratic challenger Annie Andrews.
