(CNN) - Republican presidential candidate Mitt Romney continued attacking rival Rick Perry over illegal immigration Friday.
The former Massachusetts governor responded to Perry's assertion during Thursday's GOP presidential debate that those who disagree with providing in-state tuition to the children of illegal immigrants lack a heart.
"My friend Gov. Perry said if you don't agree with his position on giving that in-state tuition to illegals, that you don't have a heart," Romney said at the Conservative Political Action Conference in Orlando. "I think if you're opposed to illegal immigration, it doesn't mean that you don't have a heart. It means that you have a heart and a brain."
Perry passed a state-based DREAM Act in Texas, which allowed children of illegal immigrants to pay in-state tuition rates, a decision he defended Thursday.
"If you say that we should not educate children who have come into our state for on other reason that they have been brought there by no fault of their own, I don't think you have a heart," Perry said.
During the debate Romney said the discount "makes no sense," and on Friday said it was a plan that "cannot be sustained."
