A Trump-endorsed Senate hopeful just scored a major leg up on incumbent Senator Lisa Murkowski. Kelly Tshibaka, who is running to unseat Murkowski, was just endorsed by the influential Maggie’s List.

Fox News reports:

Maggie’s List on Wednesday backed former Alaska commissioner of administration Kelly Tshibaka. The move was one of three endorsements made by the influential federal political action committee that was shared first with Fox News.

The endorsement of Tshibaka was the first time Maggie’s List since its founding in 2010 has backed a challenger to a female Republican member of the Senate or House of Representatives.

Murkowski, a moderate Republican with a history of working across the aisle to achieve bipartisan agreements, was one of seven GOP lawmakers in the Senate to join all 50 Democrats in voting to convict former President Trump in his February impeachment trial on charges of inciting the deadly Jan. 6 attack on the U.S. Capitol. Trump was acquitted when the Senate vote fell 10 short of the two-thirds needed to convict. Murkowski is the only one of those seven Republicans running for reelection in next year’s midterms.

Trump vowed to come to Alaska to campaign against the senator. Earlier this year he endorsed Tshibaka, and a couple of leading members of Trump’s 2020 presidential reelection inner circle are working as senior advisers on Tshibaka’s team.

Maggie’s List also endorsed Republican House candidates Esther Joy King in Illinois’ 17th Congressional District and Tanya Wheeless in Arizona’s 9th Congressional District, two Democratic-held seats the House GOP’s targeting in the 2022 midterm elections. Republicans only need to flip five seats to win back its majority.
