President Obama to hold news conference Fri.

Amid the contentious meetings between Democratic and Republican leaders over the debt crisis, President Obama is scheduled to hold a press conference at the White House tomorrow at 11 a.m. EST.

It will be the president's third one in 17 days--most recently on Monday, in which Obama said he was pushing congressional leaders for the largest possible deal to resolve the debt crisis.

A Democratic official with knowledge of today's meetingtold CBS News White House correspondent Mark Knoller that the president and the congressional leaders went through all the different parts of a deficit reduction plan. The leaders will now go back to their respective caucuses to talk about what is possible.

The meeting was described as productive and not tense, according to the official.

The official also said the president is expected to make a statement tomorrow on Thursday's deficit talks.
