Officials have reopened the Cannon House Office Building after an asbestos scare shuttered its doors from late Friday through most of Saturday.  

The Architect of the Capitol announced on its website at 11:18 p.m. Saturday that trained professionals and outside analysts had performed tests and determined air samples were "well below the regulatory limit." "Engineers and certified industrial hygienists assessed the situation and an independent, accredited lab performed a rigorous air sampling analysis," the AOC said in a statement. "The building is safe to reopen."
