Man draped in American flag jumps the White House fence on Thanksgiving day

The Obama's Thanksgiving celebrations had to be cut short after a man draped in the American flag jumped the fence of the White House.

President Obama and his family were tucking into their turkey dinner when they were put on lockdown so the Secret Service could conduct a sweep of the grounds following the security breach.

CNN reports that Joseph Caputo - who was wearing a baseball shirt, gloves and the flag as a cape when he hopped the fence - was immediately taken into custody. He also appeared to have a binder in between his teeth as he climbed the metal railings.

Joseph Caputo scaled a fence on the North Lawn at 2:45 p.m., according to Secret Service spokesperson Robert Hoback. The jumper was immediately apprehended and taken into custody. 

According to two CNN photojournalists who witnessed the incident, the men was carrying an envelope, had on a blue shirt and white pants and was cloaked in an American flag. They said the officers who detained him had their guns drawn and were accompanied by K-9 units.

Vanessa Pena, an intern on Capitol Hill, was playing tourist with her twin sister who was in town for Thanksgiving. "We were just standing there and the man came up behind us," she told CNN. "I heard him take a deep breath and say, 'All right, let's do this.'"

Pena said the man "ran through" she and her sister before he jumped over a barricade, and then the fence.

Though the White House issued an official "all clear" about two hours after the episode began, the north and south fence lines remained temporarily closed Thursday evening.
