WASHINGTON (AP) — Former Republican Representative Liz Cheney said on Wednesday that she would support Kamala Harris in the presidential election, ending weeks of speculation about the extent to which the member of a Republican dynasty turned Trump critic would support the Democrats.

Cheney, the co-chair the House of Representatives investigation in the January 6, 2021, Attackwho became a fierce Trump critic and was voted out of the 2022 Wyoming Republican primary as a result, made her announcement at an event at Duke University. In a video posted on social media, she concluded by talking about the “danger” she believes Trump still poses to the country.

“I don’t think we have the luxury of putting the names of the candidates on the ballot, especially in the swing states,” she said. “As a conservative, as someone who believes in and cares about the Constitution, I’ve thought about this carefully. Because of the danger posed by Donald Trump, not only will I not vote for Donald Trump, I will vote for Kamala Harris.”

Harris’ campaign manager Jen O’Malley Dillon said in a statement Wednesday evening: “The Vice President is proud to have won Congresswoman Cheney’s vote. She is a patriot who loves this country and puts our democracy and our Constitution first.”

Liz Cheney, the daughter of former Vice President Dick Cheney, is probably Trump’s best-known Republican critic, supporting Harris alongside other Republicans such as her former Jan. 6 committee member, former Rep. Adam Kinzinger and former Rep. Denver Riggleman. More than 200 alumni Officials from the Bush administration and previous Republican presidential campaigns of the late Senator John McCain and Senator Mitt Romney also announced their support for Harris last week.

When asked for comment, Trump campaign spokesman Steven Cheung replied: “Who is Liz Cheney and what does she do?”

Cheney was part of the Republican leadership in the House at the time of the January 6 attack, but broke with most of her caucus because Trump was responsible. She lost her leadership post and was one of the few Republicans willing to serve on the January 6 Committee, appointed by the Democrats who controlled the House at the time.
