Iowa Senator Tom Harkin was in the U.S. Capitol when it was evacuated last night after a small plane strayed into restricted Washington, D.C. airspace. Harkin says he was on the floor of the Senate, “The police came and said everybody has to get out there’s a threat. Everybody got out in a very orderly fashion and we walked to our appointed place outside and waited until the ‘all clear’ was done and we came back in.” One Congressman complained that things were too confusing, but Harkin didn’t think so.”No, I didn’t see any confusion, I things were very orderly and very good,” he said. “We were just all happy it wasn’t raining.” Harkin says the confused Congressman needs to read his manual that tells him what to do in an evacuation.Fighter jets intercepted the plane and escorted it away within minutes. The White House also went on alert but the plane was gone before the evacuation had been completed.
