Liz Cheney has become the figurehead of the Never Trumpers, Republicans seeking to loosen the former president’s grip on their party, but the Wyoming congresswoman was for him in the last election.

Newly removed from Republican House leadership, Cheney spoke to ABC’s This Week in an interview to be broadcast in full on Sunday.

Asked if she voted for Trump in 2020, she replied: “I did.”

Asked if she regretted it, she said: “I was never going to support Joe Biden and I do regret the vote. I think that it was based on policy, based on sort of substance and what I know in terms of the kinds of policies [Trump] put forward that were good for the country. But that I think it is fair to say I regret the vote.”

Cheney came out against Trump after the deadly attack on the US Capitol on 6 January, by supporters he told to “fight like hell” in service of his lie that his conclusive defeat by Joe Biden was the result of mass electoral fraud.

Most of the congressional GOP has stayed behind Trump but Cheney was one of 10 Republicans in the House to vote for his impeachment, on a charge of inciting an insurrection. Trump was acquitted at trial after only seven Republican senators could be persuaded to follow suit.
