White House Security Fence Before and After
In the wake of Friday's fence-jumping incident, the White House is stepping up security with one of the most basic defenses in its toolkit: a second, shorter fence in front of the existing one.
The new portable fence is about waist high and appears to be linked together with plastic ties.
The permanent fence, the only physical barrier in place until today, stands about eight-feet tall.
The new double barricade comes just four days after an Army veteran scaled the fence and managed to enter the executive mansion with a 3 ½ inch knife.
