President Obama will travel down Pennsylvania Avenue Friday to speak privately with House Democrats on the eve of a critical vote on health care.

The White House may be attempting to put more of a stamp on the legislation as it weaves its way through the halls of Congress, and administration officials have been forcefully pushing back against reports suggesting health care won't happen until next year.

Last night, White House Chief of Staff Rahm Emanuel and administration health care staffers huddled with Senate Majority Leader Harry Reid and leadership senators Dick Durbin, Chuck Schumer and Patty Murray on Capitol Hill.

Leadership and administration officials were mum on the details.

Meanwhile, the DNC's Organizing for America has been urging supporters to phone their member of Congress before the Saturday vote.

"We expect it to be very close," Mitch Stewart, director of OFA, wrote to the campaign's 13 million-strong email list.
