Marco Rubio may run for office again “one day.”

The Florida senator sat down for a lengthy interview with Jake Tapper for CNN’s "State of the Union" on Sunday to discuss the missteps of his failed presidential campaign.


“I’ll learn from this,” Rubio said. “And whether I run for president again one day or run for something else or do this in the business world, there are lessons I will take from this that will make me stronger and better as a result.”

Rubio dropped out of the race March 15 after failing to win the primary in his home state. When he entered the Republican presidential race, he said he wouldn't seek reelection for his Florida Senate seat this year. There was some hope in GOP circles that he might reconsider that decision, so as to give Republicans a better chance to keep the seat.

Tapper asked Rubio about some of the worst moments of his campaign, including the New Hampshire debate, at which Gov. Chris Christie mocked his repetitive use of certain phrases — “I walked right into that trap” — and deciding to go after Donald Trump on the size of his hands.

Rubio told Tapper that he had apologized to Trump for those comments in private prior to a Republican primary debate.

“I said, ‘You know, I’m sorry that I said that. It’s not who I am and I shouldn’t have done it.’ I didn’t say it in front of the cameras; I didn’t want any political benefit,” Rubio said.

As previously reported, Rubio also said he is willing to speak at the Republican National Convention in July, if asked, and he expects to attend.
