Story highlights Kasich said he does not support former Judge Roy Moore

"I want this party to be straightened out"

Washington (CNN) Ohio Republican Gov. John Kasich said on CNN's "State of the Union" Sunday that a time could come when he no longer supports the Republican Party.

"If the party can't be fixed, Jake, then I'm not going to be able to support the party. Period. That's the end of it." Kasich said in an interview with anchor Jake Tapper.

"I want this party to be straightened out," Kasich said.
