In a scathing rebuke of Trump, Sen. Lisa Murkowski, a moderate from Alaska, became the first GOP senator to call for him to step down before his presidency ends and said Wednesday’s attack on the U.S. Capitol is making her rethink being a Republican.

“I want him to resign. I want him out. He has caused enough damage,” Murkowski told the Anchorage Daily News in an interview.

“I think he should leave. He said he’s not going to show up. He’s not going to appear at the inauguration. He hasn’t been focused on what is going on with covid. He’s either been golfing or he’s been inside the Oval Office fuming and throwing every single person who has been loyal and faithful to him under the bus, starting with the vice president,” she continued. “He doesn’t want to stay there. He only wants to stay there for the title. He only wants to stay there for his ego. He needs to get out. He needs to do the good thing, but I don’t think he’s capable of doing a good thing.”

A critic of Trump’s rhetoric, Murkowski has been faulted for not doing more to stand up to the president. When Trump’s presidency was on the line, she did not vote to hear additional witnesses during the Senate impeachment trial.

Murkowski, who is part of a dwindling faction of moderate Republican lawmakers, said she could consider leaving the Republican Party. In 2010, she won reelection as a write-in candidate running as an independent after losing the GOP primary in the tea party wave year.

“But I will tell you, if the Republican Party has become nothing more than the party of Trump, I sincerely question whether this is the party for me,” she said in the interview.

Republicans can’t threaten Murkowski with a primary when her term ends in 2022. This year, Alaska passed ranked choice voting, in which candidates of any party will run in an open primary and voters will rank them in order of preference.
