WASHINGTON — A man who jumped the fence at the White House this month was on the presidential grounds for more than 16 minutes before Secret Service agents discovered his presence, officials said Friday.

Utah Congressman Jason Chaffetz, chairman of the House Oversight Committee, said the intruder rattled a door handle and looked through a window before being apprehended, the Associated Press reported.

To enter the south lawn of the White House, the intruder jumped three separate fences: A 5-foot perimeter fence near the Treasury Building, an 8-foot vehicle gate and another 3 ½-foot fence near the East Wing.

A new Secret Service timeline of the incident revealed the fence jumper scaled the first barrier at about 11:21 p.m. on March 10 — and wasn't arrested until 11:38 p.m.

The Washington Metropolitan Police Department identified the man as Jonathan Tran, 26, of Milpitas, Calif. He is charged with entering or remaining in restricted grounds while using or carrying a dangerous weapon.

President Trump was in the residence at the time but was not threatened, the Secret Service said.

"The men and women of the Secret Service are extremely disappointed and angry in how the events of March 10 transpired," a statement from the Secret Service said. The agency said it conducted 50 interviews and reviewed radio transmissions and videotape in its investigation.

That the intruder evaded detection for so long, as first reported by CNN, is the latest embarrassing breach for the security service beset by a series of failures over the past few years. In 2014, a man who jumped the north fence of the White House made it into several rooms of the residence before being apprehended.

The revelation also came the same day the Secret Service disclosed a thief stole an agency laptop containing classified plans for Trump Tower and materials about the Hillary Clinton email investigation, along with lapel pins identifying agents responsible for protecting Trump, Clinton and Pope Francis.
