Florida Senator Marco Rubio is gearing up to enter his next act in politics.
Rubio spends his days buried in the work of the Senate Intelligence Committee and is a leading advocate of bolstering election security and slapping sanctions on Russians if they interfere again in 2018.
In the hallways of the nation's Capitol, he focuses on legislative proposals or policy speeches on the Senate floor.
And back in Florida, Rubio's involved in long-running disputes over the Everglades and toxic algae blooms.
But one thing Rubio isn't doing, he says, is gearing up for a White House run in 2020.
"I'm not primarying the president, and no one else should either unless we want to lose the White House," Rubio told The Associated Press. "I'm kind of approaching every day as if the U.S. Senate is the last place I'll ever serve in public office and trying to make that meaningful."
He says he keeps in contact with the president, talking to him on the phone two to three times a month.
But Rubio is continuing to reshape his own political identity, separate from the president, and isn't ruling out another White House run somewhere down the line.
