The last House Republican leader to withhold his support for Donald Trump, Tom Emmer (MN), endorsed Trump for president on Wednesday - in the latest sign of Trump's growing momentum.

Emmer is known to be a reluctant Trump supporter, so his endorsement is a strong sign that the GOP sees Trump's nomination as inevitable despite the private wishes of many establishment Republicans to be rid of him.

Trump locks up House GOP

Trump now has the support of all of the top House Republican leaders.

Before Emmer's endorsement, Trump had already been endorsed by House Speaker Mike Johnson (LA), House Majority Leader Steve Scalise (LA), Republican conference chair Elise Stefanik (NY), and National Republican Congressional Committee Chair Richard Hudson (NC).

Emmer's endorsement is particularly humiliating, given his short-lived bid to be Speaker of the House, which was torpedoed by Trump months ago. At the time, Trump called Emmer a "globalist RINO" and said it would be a "tragic mistake" to vote for him.

But Emmer, in his endorsement, said he is "proud" to support the "clear frontrunner."

“Democrats have made clear they will use every tool in their arsenal to try and keep Joe Biden and his failed policies in power."

"We cannot let them. It’s time for Republicans to unite behind our party’s clear frontrunner, which is why I am proud to endorse Donald J. Trump for President,” Emmer wrote.

GOP bends the knee....

Trump has always had an uneasy relationship with the GOP ever since his hostile takeover of the party in 2016.

The GOP made a half-hearted effort to ditch Trump nearly three years ago, after January 6th. But with Trump widely expected to win the party's nomination for president in 2024, Republicans are lining up to kiss the ring.

Trump is also gaining support in the Republican Senate, where support for Trump has always been much more lukewarm and transactional than in the House.

Senator Lindsey Graham (R-SC), an on-and-off Trump supporter for years, recently defended Trump over January 6th and echoed anew his claims of voter fraud in the 2020 election.

Senate Minority Leader Mitch McConnell (R-KY) has yet to endorse Trump, but it seems inevitable at this rate.

After Emmer's endorsement, Trump reportedly gloated, "they always bend the knee."
