Washington (CNN) - Senate Minority Leader Mitch McConnell and staffers were on Capitol Hill on Saturday as negotiations to avoid the fiscal cliff continued.
There were no major developments at midday, Senate aides from both parties said.
They expected no details would be announced until Sunday afternoon, when Democratic and Republican members were scheduled to hold private conference meetings.
House Speaker John Boehner was in the Capitol building for a meeting Saturday morning, a senior aide to the speaker told CNN. He had a meeting with his chief of staff, the aide said, and was not planning to return to the Capitol later in the day.
President Barack Obama was working at the White House, a senior administration official said, and was in close contact with the negotiators on Capitol Hill.
Negotiations to avert the cliff - tax increases and spending cuts that Congress designed to trigger automatically in the new year - were renewed Friday when McConnell, Boehner, Senate Majority Leader Harry Reid and House Minority Leader Nancy Pelosi met for an hour behind closed doors with President Barack Obama, Vice President Joe Biden and Treasury Secretary Timothy Geithner.
Negotiators were not the only people in the Capitol: The rotunda was crowded with tourists who had ducked indoors to avoid a wet snowstorm.
