Secret Service beefs up presence after 2 White House security incidents

Washington (CNN) -- The U.S. Secret Service boosted its presence and its surveillance measures around the White House on Monday after an Iraq war veteran, who is apparently suffering from PTSD, jumped over a White House fence.
Officers patrolling the area will be out in greater numbers and will be "looking for individuals who don't look like tourists," a federal law enforcement officer told CNN.
Two security incidents in two days have raised concerns about the safety at 1600 Pennsylvania Ave.
On Friday, Omar Gonzalez hopped the north fence and sprinted just past the north portico White House doors when he was stopped, Secret Service spokesman Brian Leary said.
