Police investigated a "suspicious substance" in the office of Sen. Ron Wyden early Monday evening. The initial investigation is now clear, and there are no further threats on the office.
U.S. Capitol Police cautioned Capitol Hill staff and other personnel to avoid the area in the Dirksen Senate building.
A speaker system instructed those on the underground subway to avoid the area. Staffers were still on other floors of the building, but reporters were corralled at the end of a second floor hallway.
A group of men exiting an elevator said to a Capitol Police officer, "We have a meeting with Senator Wyden," and were turned around. Reporters were told by police to be out of sight of the office.
The Oregon Democrat spoke briefly at around 5:30 p.m., but he didn't have much new information. "All I can report to you is that our office is following standard procedures," Wyden said. "I just got off the plane from Oregon, literally." He added that "obviously" his staffers' safety is his first concern, and that he had no details on the substance. Wyden walked away from the site of his office, where firefighters and others convened.
A Wyden spokesman had no additional information about the investigation, beyond staffers being asked to remain in the office.
