WASHINGTON (CNN) -- Plainclothes investigators sent to test security at federal buildings in four U.S. cities were successful in smuggling bomb components through guard posts at all 10 of the sites they visited, according to a government report.
A GAO report cites lax security in federal buildings after investigators got bomb components past guards.
The investigators then assembled the bombs in restrooms and freely entered numerous government offices while carrying the devices in briefcases, the report said.
The buildings contained offices of several federal lawmakers as well as agencies within the departments of State, Justice and Homeland Security, which is responsible for safeguarding federal office buildings.
CNN obtained the report late Tuesday, ahead of its expected release Wednesday at a hearing of the Senate Committee on Homeland Security and Governmental Affairs.
