Sen. Roger Wicker (R-Miss.) said he is grateful for the security personnel that caught a letter that tested positive for ricin on Tuesday.
“Well the authorities are looking into it, and it makes you even more grateful for our security personnel,” Wicker told The Hill on Wednesday before a Senate Armed Services hearing.
The Senate’s offsite mail facility will be closed for the next few days for further testing and an investigation by the Capitol Policy and FBI, the Senate Sergeant at Arms said in a statement.
The letter to Wicker was postmarked from Memphis and had no return address.
Sen. Clair McCaskill (D-Mo.) told reporters Tuesday evening after senators were briefed that Capitol Police had a suspect who is known to write letters to members of Congress.
Ricin is a deadly poison found in castor beans, and can be manufactured from castor bean waste materials, according to the Centers for Disease Control and Prevention.
Wicker told The Hill that he was surprised he was targeted.
“I’ve been in Congress 19 years, and 7 years in the state legislature, and this is the first time, so it’s not something that’s expected,” Wicker said.
