(CNN) - White House mail handlers identified a "suspicious substance" - possibly the poison ricin - in a letter sent to President Barack Obama the same day a similar letter was found in a Senate mailroom, the Secret Service said Wednesday.
Both letters arrived Tuesday at off-site postal facilities set up after the 2001 anthrax attacks and have been sent to laboratories for additional tests, authorities said.FULL STORY
Washington (CNN) - An envelope that tested positive for the deadly poison ricin was intercepted Tuesday afternoon at the U.S. Capitol's off-site mail facility in Washington, congressional and law enforcement sources tell CNN.
Senate Majority Leader Harry Reid said he was told the letter was addressed to the office of Sen. Roger Wicker, R-Mississippi. 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. The package was then sent to a Maryland lab for further testing.FULL STORY
