Suspected poison mailed to senator
Authorities aren't saying whether they have a suspect in the mailing of what's believed to be poisonous ricin to Sen. Roger Wicker of Mississippi.
But a fellow senator is commenting. Missouri Sen. Claire McCaskill says the person believed to have mailed the envelope writes a lot of letters to lawmakers.
The envelope containing the suspected deadly toxin was never delivered to Sen. Wicker. It was intercepted at a Senate mail facility and will be tested again to confirm its contents.
