A California man carrying Mace roamed for nearly 17 minutes inside the secured White House perimeter before he was taken into custody on March 10, the Secret Service acknowledged Friday. The man did not enter the White House, the agency said, without further explaining the delay in his capture or details about alarms, protocols or responses that may have failed, the Washington Post reports. President Trump was in the residence at the time. Jonathan Tran, 26, of Milpitas, Calif., was detected crossing a five-foot outer fence at 11:21 p.m. and was arrested at 11:38 p.m.
The incident is believed to be the first intrusion on the White House grounds since Trump took office. Last year, the Secret Service added small spikes to the top of the six-foot fence that surrounds the White House complex. The agency also announced a plan to raise the height of the fence to 11 feet by 2018. To approach the mansion, Tran scaled two additional barriers, an eight-foot vehicle gate, then a 3 ½ foot fence. The agency said it has taken steps to mitigate lapses in security protocols as the investigation continues. The Secret Service also confirmed that a laptop computer holding sensitive security information was stolen from one of its agents in New York City.
