白宫特工处加强白宫外围安全戒备

The U.S. Secret Service has increased security outside the White House after a man jumped the fence and made it inside the building before being apprehended.

Secret Service Director Julia Pierson ordered enhanced officer patrols and surveillance along the north fence of the White House shortly after the Friday incident. She also ordered a comprehensive review of what happened when an unarmed 42-year-old man scaled the fence and entered the presidential residence, where agents seized him.

President Barack Obama and his daughters had just left the White House Friday evening in a helicopter, when the unarmed intruder scaled the north fence, ran across the lawn and entered the presidential residence, where agents seized him.

Republican lawmaker Jason Chaffetz, chairman of the House of Representatives\' subcommittee on national security oversight, called the security breach "totally unacceptable."

A Secret Service official said the agency will review its response.

A day later, on Saturday, a man was arrested for trespassing at the White House. The Secret Service said the man approached the White House gates on foot and was turned away a short time before returning to the gate in a vehicle. He was arrested when he refused to leave.

特工处处长朱丽亚·皮尔森在事件发生后不久，命令提高白宫北面围墙的警员巡逻以及监控。她还命令全面审查这一事件。此前，一位42岁的携带一把刀子的男子翻过栅栏进入了白宫，随后被特工抓捕，引发特工处对白宫进行部分紧急疏散。

奥巴马总统和他的两个女儿此前刚刚乘直升机离开白宫。共和党籍众议员、众议院国家安全小组委员会主席詹森·查菲兹说，这一事件是“完全不可接受的”。

星期六，一名男子因私闯白宫被逮捕。特工处说，这位男子步行接近白宫大门被拦回。不久，他又开着车返回大门口。特工处在他拒绝离开后将他逮捕。
