ABC News' Stephanie Z. Smith reports from Martha's Vineyard:
President Obama will end his vacation tonight, one day earlier than originally planned, White House officials said.
The president thought it would ”be more prudent for him to be in Washinton, D.C., and at the White House,” deputy press secretary Josh Earnest told reporters.
The president made the decision to cut short his family vacation on Martha's Vineyard shortly after addressing the nation about the impending danger of Hurricane Irene, which he said has the potential to be "historic."
Obama is expected to arrive back at the White House on Friday evening along with the First Lady and their daughters, Sasha and Malia.
The family had been scheduled to return to Washington together tomorrow afternoon.
