U.S. Sen. Marco Rubio has told his top donors that he will run for president in 2016, the Associated Press reported Monday. In a conference call with donors, Rubio said he was "uniquely qualified" to represent the Republican Party and that he considered the 2016 election to be a decision between America's past and America's future.

Rubio, the junior senator from Florida, was largely expected to announce his bid for the presidency Monday evening at a political rally in Miami. "This nation's in need of leadership that understands this new era and has new ideas for a new age," he said in late March, CNN reported. "And so, again, I'm looking forward to talking about that and many other things on April 13th."
