White House intruder 'had ammo and a machete in his car'
The man who broke into the White House on Friday evening had 800 rounds of ammunition, a machete and two hatchets in his car, authorities have said.
Omar Gonzalez, 42, was carrying a knife when stopped by Secret Service officers just inside the building.
On Monday, officials said he was also arrested in July with two rifles and a map marking the White House.
The Secret Service says it has stepped up security and launched a comprehensive review of procedures.
