White House break-in: security increased after man with 'three inch serrated blade' enters building

A man with a knife had broken into the White House before he was apprehended

White House security has been increased after a man with a knife broke into the presidential building on Friday.

The iconic residence was evacuated when 42-year-old Omar J Gonzalez, armed with a 3-inch serrated blade, jumped the exterior fence and entered the building via its grand North Portico door.

According to a criminal complaint, when Gonzalez was apprehended he told Secret Service agents he was "concerned that the atmosphere was collapsing" and needed to contact the president "so he could get word out to the people."

The Secret Service, who apprehended Mr Gonzalez after he entered the White House, has ordered a comprehensive review of the incident, and has stepped up security operations.

President Barack Obama has declared his continued confidence in the Secret Service despite the breach, which had happened just after he and his two daughters had left the White House by helicopter.

"The president has full confidence in the Secret Service and is grateful to the men and women who day in and day out protect himself, his family and the White House," said White House spokesman Frank Benenati.

He said they expect Secret Service Director Julia Pierson to conduct her review "with the same professionalism and commitment to duty that we and the American people expect from the U.S. Secret Service."

Another man was arrested Saturday outside the White House in an unrelated event.

"Every day the Secret Service is challenged to ensure security at the White House complex while still allowing public accessibility to a national historical site," the agency said in a statement.

"Although last night the officers showed tremendous restraint and discipline in dealing with this subject, the location of Gonzalez's arrest is not acceptable."

The Secret Service's Office of Professional Responsibility was carrying out the review, which started Friday with interviews and a physical site assessment and will include a review of all of the security and operational policies, officials said.

Officials had originally said that Gonzalez appeared unarmed as he sprinted across the lawn — potentially one reason agents didn't shoot him or release their service dogs to detain him.

But Gonzalez had a small folding knife with a 3-inch serrated blade at the time of the arrest and faces a weapons charge, according to a criminal complaint issued late Friday.

Pierson ordered enhanced officer patrols and surveillance along the North Fence of the compound following the incident.

Gonzalez, of Texas, was transported to a nearby hospital after his arrest for evaluation. He was expected to appear in federal court Monday to face charges of unlawfully entering a restricted building or grounds while carrying a deadly or dangerous weapon.

Less than 24 hours after Gonzalez' arrest, a second man was apprehended after he drove up to a White House gate and refused to leave, the Secret Service said, prompting bomb technicians in full gear to search the vehicle as agents shut down nearby streets.

There were no indications the two events were connected. Yet the pair of incidents in short succession only intensified the scrutiny of the Secret Service, which is still struggling to rehabilitate its image following a series of allegations of misconduct by agents in recent years, including agents on Obama's detail.

Gonzalez's former Texas neighbors said he moved out roughly two years ago. Sgt. 1st Class David Haslach, who lives two doors down from Gonzalez's former home, said Gonzalez had been in the U.S. military and told Haslach he had received a medical discharge.

He and another former neighbor, Elke Warner, both recalled him seeming paranoid in the months before he left town.

"At the end, he got so weird. He had motion detector lights put in," Warner said. She added that she last saw Gonzalez about a year and a half ago at a nearby camp site, where he was apparently living with his two dogs.

The Secret Service has struggled in recent years to strike the appropriate balance between ensuring the first family's security and preserving the public's access to the White House grounds.

Once open to vehicles, the stretch of Pennsylvania Avenue in front of the White House was confined to pedestrians after the 1995 bombing of the federal building in Oklahoma City, but officials have been reluctant to restrict access to the area further.
