Too much mystery around this costly little jaunt.
Check it out:

President Obama won’t make any major announcements on immigration reform during his secretive mid-vacation trip back to Washington next week, the White House said Wednesday.

The president is expected to return to the White House on Sunday, but officials won’t say why Obama is taking the unusual, and costly, trip back to Washington. He’s expected to return to Martha’s Vineyard, where he’s been vacationing, on Tuesday.

Speculation has circled around whether Obama might make an announcement of executive actions he’s taking on immigration reform, or a surprise visit from a foreign leader.
