Sen. Joe Manchin, D-W.Va., said Wednesday he regretted endorsing failed 2016 Democratic presidential nominee Hillary Clinton, adding he would be “open” to throwing his weight behind President Trump’s 2020 re-election bid.

“I’m open to supporting the person who I think is best for my country and my state. If his policies are best, I’ll be right there,” Manchin told Politico in an interview published Wednesday.
