Rubio: I'm Not Dropping Out

Struggling GOP presidential primary contender Florida Sen. Marco Rubio is vowing to maintain his White House bid, batting back reports he was considering dropping out.

With just days before a crucial primary in delegate-rich Florida, Rubio said rumors of his bowing out are "100 percent, categorically false."

"I am not dropping out, I am fighting all the way through," he tells Fox News host Megyn Kelly in a Thursday night interview about the bruising race. 

"We're going to win Florida."

The Sunshine State primary is a winner-take-all contest with 99 delegates at stake.

"We win Florida on Tuesday and this election changes completely, and it gives us the momentum to go forward to win the nomination," he declared.
