Jay Carney, the former press secretary for President Barack Obama, started his new gig as a political commentator for CNN on Wednesday night, but it didn’t go exactly as planned: By the end of the night, Obama’s second press secretary had been yelled at by none other than Republican Arizona Senator John McCain.

According to The Hill, Carney and McCain began arguing following Obama’s speech on ISIS, discussing everything from the lack of a residual force in Iraq to the strength of the military opposition in Syria.

“I’m astounded that Mr. Carney should say that the Free Syrian Army is now stronger,” McCain said. “Facts are stubborn things. The fact [Obama] didn’t leave residual force in Iraq is the reason we’re facing ISIS today. So the facts are stubborn things in history and people ought to know them.”

“You present the facts that you believe are true based on the argument that you have made for a long time, sir, that we should let in Iraq in perpetuity and that is what the president does not believe,” Carney said in response.

According to the New York Daily News, Carney tried several times to convince McCain that they would have to agree to disagree, but the former POW wasn’t in the mood.

“It’s not a matter of disagreement, it’s a matter of facts, and you have yours wrong and you have distorted them,” McCain said.
