On CBS "This Morning," Sen. Marco Rubio, R-Fla., took a shot at Hillary Clinton, the presumptive Democratic frontrunner of the 2016 presidential election.

During the interview that aired on Wednesday, Rubio explained that Republicans should not be scared of Clinton in 2016.

"I think Secretary Clinton is going to have a lot to answer for," he said. "She was the architect for the foreign policy that was put in place by this administration, and it's been a colossal failure."
