Marco Rubio Says He's Ready to Become President

Republican Senator Marco Rubio says he is ready to become the first Hispanic president of the United States, taking a swipe at potential Democratic rival Hillary Clinton.

Rubio, born in the United States to Cuban immigrants and a darling of the ultra-conservative Tea Party faction, was once considered a frontrunner for the 2016 Republican presidential nomination, but his poll numbers have dipped.

Speaking in an interview broadcast Sunday on ABC’s “This Week,” Rubio was asked if he thought that he was ready to be president.

The interview was conducted earlier in the week during a stop in New Hampshire, a critical state that votes early in the primary election cycle.

Clinton is the presumed frontrunner for the Democratic nomination, but Rubio, a Florida senator, was scathing in his assessment of her performance as secretary of state.

Rubio said “F” would be an appropriate grade to give Clinton for her recent post as secretary of state.

And Rubio dismissed a White House report warning of the serious environmental damage human activities are already causing across the United States.
