Washington (CNN) - Vice President Joe Biden answered questions from House Democrats for roughly 45 minutes Tuesday while rallying support for the fiscal cliff agreement that passed through the Senate, according to a Democratic source present at the meeting.
Biden, who was a key player in the deal brokered between the White House and Congressional leaders, spent an hour talking to members of the House Democratic caucus explaining the negotiations step by step, the source said.
He then took questions from approximately 20 members, all of whom stayed in the room until the gathering was over.
The biggest point of contention centered on a concern over the impending debt ceiling and budget fights, according to the same source. The agreement passed through the Senate provides a temporary solution to some of the country's fiscal challenges, readying negotiations in the coming months over an increase to the debt ceiling and how to fund many government agencies.
At a press conference following the meeting, Democratic Rep. Xavier Becerra described the "standing room only" meeting as "frank."
House Minority Leader Nancy Pelosi said Biden spoke to them about the details of the legislation and the potential hurdles that lie ahead, at the same event where Democratic leaders urged Republicans to bring the Senate-passed legislation to a vote.
"The speaker said that when the Senate acts we will have a vote in the House," Pelosi said. "That is what he said, that is what we expect, what American people deserve. Look forward to seeing what the timing will be for a straight up or down vote on what passed 89-8 in the Senate."
After returning from the Hill, Biden frequented the Potbelly sandwich restaurant across the street from the White House.
When asked by CNN's Lesa Jansen if there would be a fiscal cliff deal, he responded "I hope so. I think so."
