Rick Santorum today said he regrets telling me on "This Week" that John F. Kennedy's 1960 speech on religion made him want to "throw up."

"I wish that I had that particular line back," Santorum, who is also Catholic, said on Laura Ingraham's radio show today. 

On Sunday Santorum  criticized Kennedy's speech to the Greater Houston Ministerial Association saying he did not agree with Kennedy when he said "the separation of church and state is absolute."

"To say that people of faith have no role in the public square?  You bet that makes you throw up.  What kind of country do we live that says only people of non-faith can come into the public square and make their case?" Santorum asked on "This Week."

Today Ingraham, a conservative radio host, told the former Pennsylvania Senator that she believes he is a tolerant person but "sometimes Senator, when you're out there and it's like 'I'm going to throw up when I heard JFKs line on that.' I mean, as a Catholic, he's a revered president of the United States, assassinated, I probably wouldn't have gone down that road with JFK and I was going to throw up. We generally don't want to hear presidential candidates talking about throwing up at all in any context."

Santorum said he "would agree with that."
