Liz Cheney: "If [Donald Trump] is the nominee, I won't be a Republican."

Rep. Liz Cheney — a vocal critic of former President Donald Trump — has signaled that she may leave the GOP, saying, "If [Trump] is the nominee, I won't be a Republican."

"I certainly will do whatever it takes to make sure Donald Trump isn't anywhere close to the Oval Office," the Wyoming Republican told Texas Tribune CEO Evan Smith at the paper's festival on Saturday.

Cheney also said Saturday that she would be willing to stump for Democrats, the first time she has said so explicitly. The comments were made in response to a question about Wyoming gubernatorial candidate Kari Lake, a supporter of Trump's false claims that the 2020 election was stolen.
