Kevin Peterson, 23, was apprehended after scaling the iron fence shortly after 11:30 a.m., a Secret Service spokesman said. Peterson is expected to be charged with unlawful entry under District of Columbia law, according to Malcolm Wiley, a spokesman for the Secret Service. He was not carrying a weapon, Wiley said.
The spokesman would not comment further about Peterson or the incident and would not confirm President Bush's whereabouts at the time of the incident.
The Washington Post reported on its Web site that Bush was returning from a visit to the Republican National Committee headquarters, and that armed Secret Service agents were surrounding the presidential limousine outside the Oval Office as Peterson was arrested a few hundred feet away. The president emerged from the limousine several minutes later, the newspaper reported.
