Rep. Levin urges Senate to pass tax extenders

"I think it's broadly recognized that there has to be some changes to the pension provision," Levin said, adding, "That's understood in the Senate as well ... it's possible they may even include a revised doc fix in the their [new] bill."

Sources say Senate Democratic leaders are looking to fully offset an extension to the Federal Medical Assistance Percentage (FMAP) included in bill to sway at least some Republicans into supporting the bill. 

"He [Baucus] is now trying to get some Republicans to step up to the plate; that's where the emphasis is," Levin said, adding, "The ball is in the court of the Republicans. That's where the ball is."

Levin and Baucus have had several discussions to ensure that whatever does eventually pass the Senate will also be able to pass the House. 

"We've had a lot of discussions about that," Levin said.
