Former U.S. Sen. Rick Santorum of Pennsylvania intends to rally conservatives for the man who defeated him for the Republican presidential nomination -- former Gov. Mitt Romney of Massachusetts -- when the GOP holds its convention in Tampa later this month.

On Wednesday, a day after it was announced that Santorum would address the convention, the former presidential candidate said that Patriot Voices, an organization that he chairs, will hold an event for Romney in Tampa on Wednesday, Aug. 29.

"We at Patriot Voices look forward to joining with the country's leading conservative voices to demonstrate our committed support for Mitt Romney,” Santorum said on Wednesday. “Already, we've assembled a tremendous number of co-hosts that are outspoken conservatives on fiscal, social and national security issues."
