Breaking: Rick Santorum suspending his campaign

The Associated Press is reporting Rick Santorum is suspending his campaign for the GOP presidential nomination, clearing a path for Mitt Romney to become the nominee.

A campaign spokesman says the former Pennsylvania senator was to make the announcement Tuesday in his home state of Pennsylvania, two weeks before the GOP presidential primary there. Santorum faced a tough fight in his home state against Romney.

NBC’s David Gregory reports Romney has called Santorum – however Santorum did not endorse Romney in his speech today.

Newt Gingrich wasted no time going after Rick Santorum’s backers.

“I humbly ask Senator Santorum’s supporters to visit Newt.org to review my conservative record and join us as we bring these values to Tampa,” Gingrich said in a statement. “We know well that only a conservative can protect life, defend the Constitution, restore jobs and growth and return to a balanced budget.”

Gingrich commended Santorum on his presidential run, saying the former Pennsylvania senator “waged a remarkable campaign.”

The former House speaker repeated his promise to stay in the race until the nomination is clinched, even if that means taking it to the national convention in August.
