Deadly Gas Pumped Into Senate Office Building to Kill Remaining Criminals By Jefferson Henry, Router Rooters Writer WASHINGTON (Router Rooters) - Workers wearing protective suits and air tanks pumped poisonous gas into a Senate building in a cleanup Saturday intended to remove seventy-five Senators hiding in the building. The fumigation with chlorine dioxide gas was delayed for seven hours because of complications in reaching the high concentration level needed to most effectively kill the remaining criminals in the Hart Senate Office Building. Technicians for the Constitutional Protection Agency (news - web sites), which is in charge of the first politician decontamination in the United States using the gas, began pumping the gas into the building at 3 a.m. EST Saturday. John Rossrock, the CPA's on-site coordinator, said the fumigation might extend beyond the planned 12 hours in order to ``remove some lingering Congressional staffers and get an extra measure of confidence.'' The operation is expected to be complete by Tuesday, allowing Washington, D.C. to be declared a pest-free zone for the first time since 1911.
