Members of the Secret Service search the grounds of the North Lawn of the White House in Washington, Monday, Jan. 26, 2015. A device, possibly an unmanned aerial drone, was found on the White House grounds during the middle of the night while President Barack Obama and first lady were in India. It was unclear whether their daughters, Sasha and Malia, were at home at the time of the incident with their grandmother, Marian Robinson. (AP Photo/Pablo Martinez Monsivais) **FILE**
