As promised, former President Trump is throwing his influence and endorsement behind Alaskan Senator Lisa Murkowski’s challenger. Friday afternoon Trump officially released a statement endorsing Kelly Tshibaka for U.S. Senate after Murkowski voted to impeach Trump.

“Lisa Murkowski is bad for Alaska. Her vote to confirm Biden’s Interior Secretary was a vote to kill long sought for, and approved, ANWR, and Alaska jobs. Murkowski has got to go! Kelly Tshibaka is the candidate who can beat Murkowski—and she will. Kelly is a fighter who stands for Alaska values and America First,” Trump writes. “She is MAGA all the way, pro-energy, strong on the Border, tough on Crime and totally supports our Military and our great Vets. Kelly is a powerful supporter of the Second Amendment and JOBS! I look forward to campaigning in Alaska for Kelly Tshibaka. She has my Complete and Total Endorsement!”

The Hill reports:

Tshibaka first launched her campaign against Murkowski in late March, saying that the Republican incumbent no longer represents the values held by the GOP base.

“I am running for the Senate to represent our conservative Alaska values,” Tshibaka said at the time. “We’re going to defeat Lisa Murkowski and show the DC insiders what happens when Alaska has strong conservative leadership!”

While Murkowski has not yet formally launched a reelection campaign, she will be no electoral slouch if she runs for another term.

She lost the GOP primary in 2010 to a Tea Party-backed candidate but went on to win the general election as a write-in candidate.

So far, Tshibaka is the only Republican challenger to announce a campaign against Murkowski.
