What is happening in the world? A letter sent to Mississippi Sen. Roger Wicker was found to have ricin or another poison in it, according to Senate Majority Leader Harry Reid. The envelope was intercepted at an off-site Capitol facility, where it was tested and then sent to Maryland for more tests. “We were told it’s not as deadly as anthrax, but it’s still very serious,” said Senate Majority Whip Dick Durbin. Other law-enforcement officials said it was unlikely to be connected to the Boston attacks, and that ricin cannot cause mass casualties.
