Republican strategist Tara Setmayer clashed with former President TrumpDonald John TrumpTrump rallies in Nevada amid Supreme Court flurry: 'We're gonna get Brett' Trump: 'Good news' that Obama is campaigning again Trump boosts Heller, hammers 'Wacky Jacky' opponent in Nevada MORE advisor Jason Miller in a heated debate on CNN over the president's response to the Russia probe.

The two butted heads on "Anderson Cooper 360" late Monday while discussing Trump's response to new indictments by special counsel Robert MuellerRobert Swan MuellerSasse: US should applaud choice of Mueller to lead Russia probe MORE in the ongoing investigation into Russian election meddling. The new development in the Russia probe followed the deadly school shooting at a high school in Parkland, Fla., that left 17 dead and 14 others injured. 

Setmayer ripped Trump for his tweets and comments about both the shooting and the indictments, saying it "highlights how unqualified he is" to be president.

“This, again, just highlights how unqualified he is as president of the United States. He does not have the temperament. You have to be able to take the hits if you’re going to be president of the United States, and he is unable to do it," Setmayer said.


"So instead he behaves like an insecure lunatic on Twitter as opposed to being a mature adult as the president of the fricking United States. I’m sick of you guys making excuses for him," she continued. 

Miller had been defending Trump's tweets over the weekend regarding the Russia investigation, saying he was being "attacked around the clock" and that he spent time with shooting victims in Florida.

“Children were killed!” Setmayer shot back at Miller's defense of Trump.

“It’s okay if the president is attacked and he can’t push back at all?” Miller responded. “So he has to just take an attack?”

“He is the most thin-skinned person,” Setmayer responded. “He doesn’t need to defend himself all the time constantly, especially after a major national tragedy where kids died miles from his resort where he’s living in luxury.”

The CNN debate took place after Trump traveled to South Florida on Friday to meet with the families and friends of victims of the shooting. But he also issued a slew of tweets on Saturday and Sunday reacting to the special counsel's new indictments in the Russia probe.

He also suggested the FBI failed to address red flags regarding the alleged shooter, Nikolas Cruz, because they were too busy with the Russia probe.
