AN intruder has been arrested at the White House after breaching its security.
The paper said authorities did not find risky materials inside the backpack following a screening.
The incident unfolded despite a series of recommendations to tighten security after a 2014 intrusion that led to the resignation of Secret Service director Julia Pierson.
"Secret Service did a fantastic job last night", President Trump told reporters Saturday.
An earlier report by CNN identified the suspect as a male with a California driver's licence.
Mall in German city of Essen remains closed over threat
Reports said police officers, many armed with machine pistols and bullet-proof vests, had even forced out early morning staff. A shopping centre in the north-western German city of Essen was shut by police on Saturday over fears of an imminent attack.
The comment came as the president was beginning a meeting with Cabinet officials at a golf course he owns about 25 miles outside Washington. "I have an appointment", he said when approached by an officer.
This is the first time there has been a security breach under the Trump Administration, however, not the first time the White House has seen this type of activity.
The officer asked Tran how he got onto the grounds and he allegedly said, "I jumped the fence". Construction of the new fence is expected to begin by next year, Reuters reported the Secret Service had said.
The previous year, Omar Gonzales made it through the north portico doors with a knife.
Joseph Caputo, carrying an envelope and cloaked in the American flag, leapt over the White House fence. He was later given an eight-month sentence.
