Sen. Ted Cruz (R-TX) doesn’t have the right temperament to campaign for president, GOP frontrunner Donald Trump said during a campaign rally in South Bend, Indiana.

“I got this guy, Cruz, lyin’ Ted. I think he’s crazy. Honestly, I think he’s crazy,” Trump said at the Century Center, after alleging Cruz lied about Trump’s position on Obamacare and building the U.S.-Mexico border wall.

“Lyin’ Ted does not have the temperament to be doing this,” Trump said.

“He’s choking like a dog because he’s losing so badly. We have to put him away tomorrow,” Trump said, citing the Indiana primary on Tuesday. “Get out and vote!”
