Senate Democratic leaders have arrived at the White House for what administration officials are calling a "check-in."

Senate Majority Leader Harry Reid (D-NV), Majority Whip Dick Durbin (D-IL) and Sens. Chuck Schumer (D-NY) and Patty Murray (D-WA) will be meeting with President Obama and (probably) top health care adviser Nancy-Ann DeParle and chief of staff Rahm Emanuel, who have been on Capitol Hill all week helping negotiate the merger of the two versions of the Senate health care plan.

A source tells TPMDC there isn't a laser focus on all of the public option news breaking over on the Hill (Brian's latest is here) but rather a talk about everything being floated as a potential compromise.

"I think there are a lot of moving parts here and don't think anything is close to being settled," the source said.

Speaker Nancy Pelosi (D-CA) had a private lunch with Obama today and aides on both sides are mum on what they discussed.

TPMDC is camped out here at the White House to get a sense of how the talks are going, and we'll keep you posted.
