An anonymous reader sends word that the Secret Service is investigating a "device," described as a small drone, found on the grounds of the White House. "A small drone was found on the White House grounds overnight, two law enforcement sources told ABC News, but White House Press Secretary Josh Earnest said the situation 'does not pose any sort of ongoing threat.' The Secret Service is investigating the device, Earnest said. Police, fire and other emergency vehicles swarmed around the White House in the pre-dawn hours, with several clustered near the southeast entrance to the mansion. The White House was dark and the entire perimeter was on lockdown until around 5 a.m., when pass holders who work in the complex were allowed inside."
