Washington (CNN) – An envelope that tested positive for the deadly poison ricin was intercepted Tuesday afternoon at the U.S. Capitol’s off-site mail facility in Washington, congressional and law enforcement sources tell CNN.
Senate Majority Leader Harry Reid said he was told the letter was addressed to the office of Sen. Roger Wicker, R-Mississippi. A laboratory in Maryland confirmed the presence of ricin after initial field tests indicated the poison was present, according to Senate Sergeant-at-Arms Terrance Gainer.
However, the FBI said additional testing is needed as field and preliminary tests produce inconsistent results.
Sen. Roger Wicker is one of the Republican senators who voted to end the filibuster on universal background checks.
Honestly, I only knew what ricin was because of Breaking Bad.
