President Obama's somewhat mysterious return to the White House from his Martha's Vineyard vacation starts late Sunday night.
The president is expected to have meetings at the White House on Monday and Tuesday, including national security sessions on the Iraq military operation.
The president's brief trip -- he is scheduled to return to Martha's Vineyard on Tuesday, and stay there the rest of the week -- has inspired all sorts of speculation.
Obama is on track to announcement major executive orders on immigration policy. But aides said that won't happen this week.
"I can assure you we are not anticipating a major announcement on immigration when the President is in Washington," said White House spokesman Eric Schultz last week.
The Obama administration had been planning a major rescue operation involving religious minorities trapped on a mountain in Iraq. But a Pentagon assessment team said last week that many people have been evacuated, and a rescue operation would not be necessary.
Obama is scheduled to be back at the White House at around 11 p.m. Sunday. Stay tuned for what happens over the next two days.
