Trump repeatedly said during the CNN event in Houston that the centerpiece of his plan to replace ObamaCare was allowing insurers to cross state lines.

"Now he's the one repeating himself," Rubio said, interrupting the business mogul.

The billionaire businessman struck back, noting Rubio's past debate flub.

"I watched him repeat himself five times four weeks ago," he said.

"I saw you repeat yourself five times five minutes ago," the Florida senator quickly shot back.

"He says five things: Everyone is dumb, he's going to make America great again, win, win, win, he's rising at the polls, lines around the state," he said to another round of applause and laughter.

Rubio was roundly mocked for repeating a prepared answer during an early February debate even after Chris Christie, who has since dropped out of the race, called him out for it.

Rubio later blamed that performance for his poor showing in New Hampshire.
