"The White House announced Obama's trip as he headed to the University of Michigan to give the commencement address on Saturday. Word about where the president would go was expected later Saturday. He intended to take a smaller than usual entourage."
The visit comes as Florida declares an emergency over the spill. Florida Sen. Bill Nelson has asked Obama to back off plans for opening up part of the Outer Continental Shelf to oil drilling; Sen. George LeMieux, who had said he'd be open to some oil drilling, is scheduled to fly over the spill area Monday with Sen. Jeff Sessions, R-Ala.
