Envelope Sent To Senator's Office Tests Positive For Ricin Poison
Quoting "congressional and law enforcement sources," CNN is reporting that an envelope sent to a senator's office has tested positive for the poison ricin.
"After the envelope tested positive in a first routine test, it was retested two more times, each time coming up positive, the law enforcement source said," CNN reports. "The package was then sent to a Maryland lab for further testing."
Quoting "two sources," Politico reports the envelope was sent to the office of Sen. Roger Wicker, a Republican from Mississippi.
NPR's Tamara Keith reports that Senate Majority Leader Harry Reid, D-Nev., said the package was sent to Wicker's office and it contained ricin or some other poison.

Update at 6:35 p.m. ET. What Is Ricin?
"Ricin is a poison found naturally in castor beans," the CDC writes in its fact sheet. "If castor beans are chewed and swallowed, the released ricin can cause injury. Ricin can be made from the waste material left over from processing castor beans."
The Washington Post reported back in 2004, that ricin is "twice as deadly as cobra venom."
