GOP Rep. Chaffetz Changes Course, Says He'll Vote For Trump

Republican congressman Jason Chaffetz, who hails from the newly-minted toss-up state of Utah, seemingly has had a change of heart: He now says he will indeed vote for Donald Trump.

"I will not defend or endorse @realDonaldTrump, but I am voting for him. HRC is that bad. HRC is bad for the USA," Chaffetz tweeted Wednesday night.

But earlier this month -- after audio of Trump bragging to former "Acccess Hollywood" host Billy Bush about sexually assaulting women was leaked -- Chaffetz told ABC News Radio, "I don't plan on voting for Donald Trump ... this is quite the quandary what the nation's going to have to figure out."

And during another interview with ABC News after the audio's release, Chaffetz said, "I'm out, I can't support Trump after his lewd comments."

When contacted by ABC News Wednesday night, Chaffetz declined to elaborate on his latest tweet, saying, "hopefully it speaks for itself."

As chairman of the House Oversight and Government Reform Committee, Chaffetz has led the charge into investigating then-Secretary of State Clinton's role in the 2012 Benghazi terror attack, as well as her use of a private email server and the deletion of more than 30,000 emails from that account.
