WASHINGTON -- Sharp differences emerged on Sunday between House and Senate Republicans over the prospect for a budget deal with President Barack Obama, with House Speaker John Boehner (R-Ohio) insisting that "the talk about raising revenue is over" even as Sen. Bob Corker (R-Tenn.) said that the GOP is open to increasing tax receipts by closing loopholes.

"I think there, by the way, is a chance on a deal," Corker told Fox News' Chris Wallace. "I think the president is saying the right things. We have an opportunity over the next 4 to 5 months."

"I think Republicans, if they saw true entitlement reform, would be glad to look at tax reform that generates additional revenue. And it doesn't mean creeping rates, it means closing loopholes. It also means arranging our tax system so we have economic growth. And I think we have been saying that from day one."
