What did JD Vance say about Donald Trump?

Vance didn't always like the former president.

He previously suggested that Trump could be “America's Hitler” and compared him to an opioid – a quick fix that wouldn't actually solve the country's problems. Vance did not vote for Trump in 2016 and joked that he would rather put his dog on the ballot than support him or Hillary Clinton.

“I think I'm going to vote third party because I can't stand Trump,” Vance told NPR. “I think it is harmful and takes the white working class to a very dark place.”

Vance changed his tune as he prepared for his 2022 Senate run, deleting controversial tweets and praising Trump for the work he did in office. He secured Trump's support in a messy Republican Senate primary and is now one of the former president's staunchest allies.
