Rubio Addresses Critics Who Say Now's Not His Time: 'I've Heard That Before'

Midway through Rubio’s speech, immigration activists interrupted the Florida senator, shouting that he should protect President Obama’s executive action for young illegal immigrants.

“That’s the difference between Cuba and the United States – if you do that in another country, your family’s house would be raided, your family’s business would be shut down,” he said. “In America, people have the right to interrupt speeches. They have the right to be rude. They have the right to be wrong."

After the protesters were escorted out of the room, the activists told PJ Media they were from various groups including United We Dream, M.E.Ch.A and Deferred Action for Parental Accountability.

Republican presidential candidate Sen. Ted Cruz (R-Texas) focused on protecting religious liberty in his speech at the conference.

“The modern Democratic Party has decided that their commitment to mandatory gay marriage in all 50 states trumps any willingness to defend the First Amendment,” Cruz said.

He stressed the importance of motivating evangelical Christians to vote in the 2016 presidential election.

“It's a real simple formula,” Cruz told the conference. “If people of faith show up, if we stand for our faith and our liberty and the Constitution, we will win and turn the country around.”

Republican presidential candidate Sen. Rand Paul (R-Ky.) said he entered the race to take power away from the federal government and give it back to the American people.

Paul said Republicans have to explain their positions on a host of issues to different groups of voters.

“We need to be the party of the entire Bill of Rights,” Paul said, mentioning the right to privacy.

“I’ve tried to champion that I’m all for looking at the records of terrorists but I want to do it with a warrant with a judge’s name on it.”
