President urges own party to vote for tax compromise with Republicans.
The White House is trying to mend fences with angry Democrats.
Many in the President's party believe he gave away too much to Republicans when he agreed to an extension of the Bush-era tax cuts.
The president argued Wednesday that it's a compromise that will help the economy, and the middle class, in the long run.
The GOP had threatened to let taxes go up on everyone if taxes went up on the wealthy.
"Let them tell the middle class they won't give them a tax cut. Let them tell the unemployed
they can't have relief," argued Democratic Arizona Representative Raul Grijalva.
"I'm not sure this bill can pass in this form in the House of Representatives," warned Maryland's Chris Van Hollen.
Vice President Biden spent a second day on Capitol Hill to make the case for compromise.
The White House insists this isn't a defeat for Democrats.
"It's a far better deal in terms of jobs and economic growth protection for the middle class then
anyone could have expected," says Jared Bernstein, Vice President Biden's chief economist.
The president is telling Democrats to go ahead and debate, "But get this done," he said. "The American people are watching and they're expecting action on our parts."
Some Democrats are convinced there's still room and time for negotiation and want to tweak parts of the bill to get a better deal.
