Liz Cheney hits the campaign trail with Kamala Harris four years after calling her a 'radical leftist'

Former Rep. Liz Cheney will hit the campaign trail Thursday with Vice President Kamala Harris four years after calling her a 'radical leftist.' 

When Harris was picked to be President Joe Biden's VP, Cheney blasted the choice saying the then-California senator had a 'more liberal voting record than Bernie Sanders & Elizabeth Warren.' 

Cheney warned that Harris' liberal positions on abortion, immigration and healthcare 'would be devastating for America,' in a tweet from August 2020. 

But on Thursday, the former Wyoming lawmaker will make her endorsement of the Democratic nominee official by appearing alongside her in Ripon, Wisconsin - considered the birthplace of the Republican Party. 

Cheney announced in September that she would be voting for Harris after being ousted by Wyoming voters over becoming Congress' most prominent anti-Trump Republican. 

'And as a conservative and as someone who believes in and cares about the Constitution, I have thought deeply about this, and because of the danger that Donald Trump poses, not only am I not voting for Donald Trump but I am voting for Kamala Harris,' she said at an appearance at Duke University in North Carolina, a vital swing state.

Days later she revealed that her father, former Vice President Dick Cheney, would be casting a ballot for Harris too. 

'Dick Cheney will be voting for Kamala Harris,' she said at the Texas Tribune Festival in Austin. 

While Cheney's fellow Republican member of the House Select Committee on January 6, ex-Rep. Adam Kinzinger, took the stage in August at the Democratic National Convention in Chicago, until Thursday she hadn't appeared publicly for the Harris campaign. 

She excused her convention absence because 'I wanted to make the announcement, to do it in a way that wasn't connected to the party politics of the moment.'

'I also happened to be in London at the Taylor Swift concert,' Cheney confessed.

Swift also endorsed Harris in September. 

Ripon is significant because the one-room schoolhouse there, built in 1853, is a National Historic Landmark for its role as being the site of meetings that helped form the Republican Party in 1854. 

The Harris campaign is trying to peel away Republican and independent voters from Trump, playing up his role in January 6 and refusal to admit he lost the 2020 election - the same reasons Cheney, Kinzinger and other ex-Trump aides say they're not supporting him.

Those attacks were given new fuel this week after Trump's running mate, Ohio Sen. J.D. Vance, refused to answer a question posed by Harris' VP pick, Minnesota Gov. Tim Walz, during Tuesday night's vice presidential debate.

Walz asked Vance who won the 2020 election. 

'Tim, I'm focused on the future. Did Kamala Harris censor Americans from speaking their mind in the wake of the 2020 Covid situation?' Vance replied. 

Walz scoffed and called that a 'damning non-answer.' 

Additionally on Wednesday, Special Counsel Jack Smith unveiled stunning new evidence in a fresh filing for Trump's federal January 6 case. 

The 165-page filing casts Trump's efforts to claim victory regardless of the actual result as a plot by a private individual to steal the election, trying to get around the Supreme Court's immunity decision. 

Allies and aides are quoted as saying they wanted to 'sow confusion' about the election result, with instructions to 'make them riot.'
