Marco Rubio Says Donald Trump's Muslim Ban 'Never Going to Happen'

The Florida senator spoke with ABC News on "Good Morning America."

"All the talk, including the newscasts, are dominated by this plan that’s never going to happen," Rubio told ABC News' George Stephanopoulos on "Good Morning America" this morning.

"We need to refocus here on the important issue of terrorism," he said. "This is a growing threat and we’re not spending nearly enough time focusing on it."

He added that he believes Trump is not going to be the Republican nominee for the 2016 presidential election.

"We need to nominate someone who actually has a chance to win in the general election," he said. "I'm not going to hyperventilate about polls."

"You cannot defeat ISIS just by airstrikes," he said.
