Sen. Marco Rubio took to the floor of the U.S. Senate Wednesday afternoon, to address concerns that have arisen from some grassroots conservatives over his support of immigration reform.

“I have received numerous emails and calls from conservatives and tea party activists,” he said at the beginning of his remarks.

“To hear the worry, anxiety, and growing anger in the voices of so many people who helped me get elected to the Senate, who I agree with on virtually every other issue, has been a real trial for me,” he confessed.

But he said he told them that he would go to Washington to “fight to stop what is bad for America,” and that what we have now is, in fact, hurting America. “I simply wasn’t going to leave it to Democrats alone to try to figure out how to fix it.”

“I got involved because I knew that if conservatives didn’t get involved in shaping this legislation, it would not have any border security reforms our nation desperately needs,” Rubio said.

Rubio asked tea party conservatives who are upset to understand that he honestly believes “it is the right thing for our country.”

And he assured them he would continue to fight along side them for “real tax reform, lowering the debt, balancing our budget, reducing regulations, rolling back job-killing environmental policies and repealing the disaster of Obamacare,” and to defend “the sanctity of life and traditional marriage.” Watch video here:
