U.S. Senate offices will begin receiving mail again on Monday after a scare involving ricin-laced letters temporarily stopped deliveries.
In an email to Senate offices, Senate Sergeant-at-Arms Terrance Gainer says that Senate mail will temporarily be screened at a House mail sorting facility but that all offices will start getting mail again on Monday.
On Wednesday, police arrested Paul Kevin Curtis, of Corinth, Miss., and charged him with sending threatening letters containing the poison and addressed to President Barack Obama and Mississippi Republican senator Roger Wicker.
Authorities say Curtis sent a third threatening letter to a Mississippi judge, though that letter is still being undergoing tests for the presence of ricin. Curtis has denied making the ricin and mailing the letters.
Gainer says the Senate's mail processing system "worked precisely the way it was intended." The letter to Wicker was intercepted at a screening facility in Landover and never reached the Capitol itself.
Gainer is also emphasizing to Senate staff that they continue to follow protocols for opening mail.
