For a change, it was Sen. Marco Rubio (R-FL) hammering another GOP candidate on Thursday for sticking to a script when he attacked Donald Trump for repeating himself.
"He says five things: everyone's dumb, he's going to make america great again, win win win," Rubio said.
The confrontation started during an exchange regarding health care policy plans.
"You'll have competition. You'll have so many plans," Trump said.
"Now he's repeating himself," Rubio responded, drawing an extended cheer from the audience during the debate in Houston.
"I don't repeat myself," Trump said after a few seconds, before pointing at the senator and saying, "He repeats himself. Here's the guy who repeats himself."
"You repeat yourself every day," Rubio shot back while the crowd continued to cheer.
Trump then noted that Rubio was visibly uncomfortable when New Jersey Gov. Chris Christie accused him of repeating himself during a prior debate.
"I watched him repeat himself five times four weeks ago," Trump said.
"I saw you repeat yourself five times five seconds ago," Rubio countered.
