"Then, he asked for a full-length mirror ... maybe to make sure his pants weren't wet, I don't know," the Florida senator said.

There is little doubt at this point that GOP presidential candidates Donald Trump and Marco Rubio disdain each other. 

The morning after a highly contentious debate on Thursday, the two men continued to take swings at one another, both accusing the other of having a "meltdown" either on stage or behind the scenes. 

In a series of tweets, the billionaire businessman said the Florida senator was a "choke artist" and in a since deleted tweet, a "little boy." 

Why would the people of Florida vote for Marco Rubio when he defrauded them by agreeing to represent them as their Senator and then quit!

Lightweight Marco Rubio was working hard last night. The problem is, he is a choker, and once a choker, always a choker! Mr. Meltdown.

Rubio fired back at Trump, reading some of the former Apprentice host's tweets — which had misspellings — during a rally. 

"Let me tell you something, last night, during two of the breaks he went backstage, he was having a meltdown," Rubio said. "First he had this little make up things applying make up around his mustache because he had one of those sweat mustaches. Then, he asked for a full-length mirror ... maybe to make sure his pants weren't wet, I don't know."

A request for response from Trump's campaign was not immediately returned.
