Speaker John Boehner (R-Ohio) and President Obama met Thursday at the White House for fiscal talks amid increasing pessimism the two can hammer out a deal before Christmas.

The 50-minute long Oval Office meeting was the first between the two since Sunday. It followed a day of harsh rhetoric and attacks that suggested Obama and Boehner were digging in rather than narrowing their differences on taxes and entitlements.

Aides to Obama and Boehner described the meeting as “frank” and emphasized that “the lines of communication remain open.” Treasury Secretary Tim Geithner and White House director of legislative affairs Rob Nabors also participated in the meeting, the administration confirmed.

Earlier on Thursday, a visibly frustrated Boehner used a press conference to rip Obama for not taking spending cuts seriously.
