AUSTIN, Texas — U.S. Sen. John Cornyn, R-Texas, endorsed former President Donald Trump for president Tuesday night after the GOP front-runner was projected to win the New Hampshire Republican primary.

Cornyn announced his endorsement on X, formerly known as Twitter, and urged his party to unite around one candidate “to beat Biden.”

“It’s clear that President Trump is Republican voters’ choice,” the post said. 

The senator went on to say that he was proud of Trump’s first term in the Oval Office. 

“I am proud of our accomplishments in President Trump’s first term, including the confirmation of 234 federal judges, including three members of the United States Supreme Court; passing historic tax reform, the Tax Cuts and Jobs Act; unleashing our energy potential; and ushering in the best economy for all Americans in my lifetime,” the post said. 

Cornyn is not the first Texas senator to endorse Trump. After Trump won Iowa’s Republican caucuses, Sen. Ted Cruz endorsed Trump on Fox News. They join nearly 30 of their senatorial colleagues in endorsing Trump.

Trump was projected to win the New Hampshire Republican primary Tuesday night by the Associated Press ahead of his sole opponent, former U.N. Ambassador Nikki Haley. The next election is in Nevada, but Trump and Haley are running in different races, with Haley running in the primary on Feb. 6 and Trump running in the caucuses on Feb. 8. After that, it is on to South Carolina on Feb. 24, where Trump is favored by 35 percentage points over Haley.
