Vice President Joe BidenJoe BidenDemocrats redefine center as theirs collapses Speculation swirls around whether Bloomberg will make Las Vegas debate stage Pelosi: 'I'm not counting Joe Biden out' MORE said Wednesday he is "confident" a budget will emerge from Congress containing all of the Obama administration's priorities intact.

Speaking before lunching with House Speaker Nancy Pelosi (D-Calif.), Biden predicted the administration would get the budget it wants from the House and Senate.

"I am confident that with the leadership of the speaker and with Harry Reid, we're going to get our budget with all the major elements intact," Biden said. "I think our budget will, I'm absolutely confident will cut the deficit in half within five years."

Some lawmakers, especially Republicans, have wondered publicly whether the budget can accommodate the Obama budget can pay for the administration's simultaneous priorities on tax relief, healthcare, the environment, and other issues.

Biden also expressed some nostalgia on his return to the Hill.

The vice president said he snuck over Senate to see former colleagues, only to be asked where he was going.

"This is a continuation of an ongoing dialogue," Biden joked of the budget talks. "We've had most of it down at the White House, but when the speaker invited me to lunch, it's a free lunch, so I decided to come on up."
