A U.S. Secret Service Uniformed Division officer and his dog stand watch at the north fence of the White House, along Pennsylvania Avenue, September 22, 2014. A man who scaled the fence and ran into the White House on Friday night had more than 800 rounds of ammunition in his car and had been arrested in July with a sniper rifle and a map marking the executive mansion, a federal prosecutor said on Monday.
