In an interview on ABC's "This Week," he said presumptive Republican presidential nominee Mitt Romney has not asked him to be his running mate, though he is focused on helping the former Massachusetts governor win the election.
"I wish Governor Romney the best, and I'll do whatever I can to be helpful to him," Santorum said. "If he calls me, I'll answer the phone call. But I'm not anxious to get back involved in the fray right now. I've got to take responsibility for my seven kids, and Karen and I have a lot of work to do."
Santorum said he's focused on the 501(c)4 political advocacy organization he recently set up called Patriotic Voices to advance conservative issues and help Romney and other conservatives get elected across the country.
"We're focused on trying to do what we can to help Governor Romney, help candidates all across this country by rallying conservatives, getting them excited about this race and the importance of it," he said.
