President Obama said an 11th-hour agreement to avert year-end tax hikes on 98 percent of Americans is "within sight" but not yet complete with just hours to go before the nation reaches the so-called fiscal cliff.
"There are still issues left to resolve but we're hopeful Congress can get it done," Obama said at a midday White House news conference. "But it's not done."
Congressional and White House negotiators have forged the contours of an agreement that would extend current tax rates for households making $450,000 or less; raise the estate tax from 35 to 40 percent for estates larger than $5 million; and prevent the Alternative Minimum Tax from hammering millions of middle-class workers, sources said.
The deal would also extend for one year unemployment insurance benefits set to expire Tuesday, and avert a steep cut to Medicare payments for doctors.
"I can report that we've reached an agreement on the all the tax issues," Senate Minority Leader Mitch McConnell said in an afternoon speech on the Senate floor.
But Sen. John McCain, R-Ariz., was among the less conciliatory Republicans.
Rather than staging a "cheerleading rally," he said, the president should have been negotiating the finishing touches of the deal.

"What did the president of the United States just do? Well, he kind of made fun, he made a couple of jokes, laughed about how people are going to be here for New Year's, sent a message of confrontation to the Republicans," McCain said. "I guess I have to wonder, and I think the American people have to wonder whether the president really wants this issue resolved or is it to his short-term political benefit for us to go over the cliff?"
McCain said the president's speech today "clearly will antagonize members of the House," and "that's not the way presidents should lead."
Both sides remained at odds on what to do about the other significant piece of the "fiscal cliff" -- the more than $1 trillion of automatic cuts to defense and domestic programs set to begin tomorrow.
The White House has proposed a three-month delay of the cuts to allow more time to hash out details for deficit reduction, while many Senate Democrats want a flat one-year delay. Republicans insist that some spending cuts should be implemented now as part of any deal.
"In order to get the sequester moved, you're going to have to have real, concrete spending cuts," Rep. Mike Rogers, R-Mich., said. "[Without that], I don't know how it passes the House."
Vice President Joe Biden and McConnell, R-Ky., have been locked in behind-the-scenes negotiations for much of the day, sources said, following several "good" conversations that stretched late into Sunday night.
"We are very, very close," McConnell said today. "We can do this. We must do this."
If a deal is reached between Biden and McConnell, members in both chambers would still need to review it and vote on it later today. Passage is far from guaranteed.
"This is one Democrat that doesn't agree with that at all," Iowa Democratic Sen. Tom Harkin said of the tentative deal. "No deal is better than a bad deal, and this looks like a very bad deal the way this is shaping up."
"I don't see how you get something voted on today," Rogers said. "Even if they get a handshake deal today, you have to put the whole thing together and that's probably not going to happen before midnight. So it would make sense to roll into tomorrow to do that."
