Former Michigan GOP Rep. Fred Upton endorses Democrat Kamala Harris for president

Former Michigan GOP Rep. Fred Upton has endorsed Democratic presidential nominee Kamala Harris over party nominee Donald Trump, of whom he's been a critic.

Upton, a former House Energy and Commerce Committee chairman, on Thursday told the Detroit News that Trump, a former president, is "divisive" and that he has "not changed his colors."

"He's still talking about the election being stolen, trashing women left and right," he said, while at a campaign event in battleground state Michigan with Democratic vice presidential nominee Minnesota Gov. Tim Walz. "We need to move forward, and that's why I'm where I am."
