A mail center that services U.S. Senate offices intercepted a suspicious letter intended for Sen. Roger Wicker (R-MS) which has
tested positive for the poison ricin, according to
Politico:
It was not immediately clear when the envelope was received. But it arrived in a Senate mail facility, which has now been closed for more testing. All congressional mail will now be processed through the U.S. House facility.
The Senate went into recess shortly after 6 p.m. Homeland Security Secretary Janet Napolitano and FBI Director Robert Mueller were briefing senators on Tuesday afternoon. A DHS official said that the briefing was intended to address cyber-security, but that the letter involving Ricin came up. [...]
Sen. Claire McCaskill (D-Mo.) said members were briefed that the substance had been found in a letter and a suspect has been identified. [...]
Senate Majority Leader Harry Reid (D-Nev.) confirmed the letter was sent to Wicker’s office and said at this point, the incident appeared to be a solitary one.
McCaskill also said that state offices for senators, which receive mail directly, were being briefed on what to look out for in mail received.
