Presidential candidate Marco Rubio called fellow GOP candidate Donald Trump a "touchy and insecure guy" who is not well informed.
"He had a really bad debate performance last week," Rubio said during an interview. "He's not well informed on the issues. He really never talks about issues and can't have more than a 10-second soundbite on any key issue. And I think he's kind of been exposed a little bit over the last seven days, and he's a very touchy and insecure guy and so that's how he reacts, and people can see through it."
Trump called Rubio a "lightweight" during the second GOP debate last week.
