President Obama addresses the nation live Tuesday night at 8 ET with the latest on the BP oil disaster. Stay with CNN for updates on the cleanup and effort to stop the leak
(CNN) -- President Obama will continue his Gulf Coast visit Tuesday with a stop in Florida's Panhandle, where beaches have started to see signs of oil as crude continues to gush from a ruptured deepwater well.
Obama, on his fourth trip to the region since oil began spewing from the well in April, is scheduled to return to Washington later Tuesday and address the nation about the situation from the Oval Office.
But first, Obama will give a speech of support for oil-impacted communities and American troops while at Pensacola's Naval Air Station Tuesday morning, an administration official said.
Meanwhile Rep. Ed Markey, D-Massachusetts, will have a chance to grill executives from five major oil companies on Capitol Hill.
The witness list for Tuesday's hearing of his House Energy and Environment subcommittee includes chief executives of BP, ExxonMobil, Chevron, ConocoPhillips and Shell Oil.
