Marco Rubio: I Embarrassed My Kids With Personal Attacks On Donald Trump

Lagging far behind in the crucial delegate count to win the Republican presidential nomination, Sen. Marco Rubio (R-Fla.) seemed to concede on Wednesday that his decision to go after Donald Trump in personal terms hurt his prospects. 

The Florida Republican insisted that he felt a responsibility to stand up to Trump, arguing that the businessman had bullied too many minority groups, journalists and fellow candidates to not be called out. But, he added, he wouldn't have mocked Trump on such trivial matters as his penis size, his face and his tan, if he had to do it again.
