defensive in testimony

At the Capitol, Democratic and Republican lawmakers alike expressed the view that the Sept. 19 breach of White House security had blemished the storied agency, and several pressed for an independent inquiry into what went wrong. They were not assuaged by Pierson's vow that "I'll make sure that it does not happen again" or by the agency's own investigation. "I wish to God you protected the White House like you protected your reputation here today," Democratic Rep. Stephen Lynch told Pierson at a public hearing that was followed by a classified, closed-door briefing. Rep. Chaffetz said afterward: "The more I learn, the more it scares me." Calm but defensive in testimony before the House Oversight and Government Reform Committee, Pierson disclosed that shortly before the intruder jumped the fence at least two of her uniformed officers recognized him from an earlier troubling encounter but did not approach him or report his presence to superiors. On Aug. 25, Army veteran Omar J. Gonzalez was stopped while carrying a small hatchet near the fence south of the White House, Pierson said. Weeks later, the same officers observed him "for some time" on the Pennsylvania Avenue north side but never intervened. Gonzalez later went over the fence, sprinted to the unlocked front door and ran through half the first floor of the White House before being tackled. Gonzalez was indicted Tuesday on a federal charge of entering a restricted building while carrying a deadly weapon and two violations of District of Columbia law.
