Washington (CNN) -- President Barack Obama told GOP leaders behind closed doors Tuesday that he had failed to reach across party lines enough during his first two years in office, a senior administration official told CNN.
He promised to do a better job of bipartisan outreach in the days ahead, the official added.
"The president said he had to do better, and the president is ready to do his part," the official said.
The list of attendees at Obama's long-awaited post-election meeting with the newly empowered congressional Republicans included Vice President Joe Biden, Treasury Secretary Tim Geithner, House Speaker Nancy Pelosi, House Minority Leader John Boehner, Senate Majority Leader Harry Reid and Senate Minority Leader Mitch McConnell.
Boehner, the top Republican in the House, is set to become speaker in January.
Boehner also said Obama told him that he "didn't spend enough time" working with the Republicans since taking office.
The president said after the meeting that he has invited Republican and Democratic congressional leaders to meet with him again several times in the future, including for a Camp David summit -- an idea considered by the administration for several weeks.
