Story highlights Marco Rubio told reporters Wednesday that he would take back his decision to personally attack Donald Trump

The Florida senator ramped up personal attacks against the real estate mogul late last month

Hialeah, Florida (CNN) Sen. Marco Rubio says if he could do it all over again he wouldn't have gone personal with insults to Donald Trump.

"At the end of the day, you know it's not something I'm entirely proud of," the Florida Republican told MSNBC during a town hall airing Wednesday night. "My kids were embarrassed by it, and if I had to do it again, I wouldn't."

But Rubio told NBC's Chuck Todd in a clip released early by the network that aside from the personal insults, Rubio stands behind his attacks on Trump's business record.

He repeated the regret in an interview with Fox's Megyn Kelly filmed before a live audience at his rally here Wednesday evening.
