Republican Senator Roger Wicker of Mississippi received a letter that tested positive for ricin.
An envelope sent to an office of Sen. Roger Wicker (R-Miss.) included a substance that has tested positive for Ricin, two sources say.
It was not immediately clear when the envelope was received or whether it was sent to his Washington, D.C., office or a field office.
Homeland Security Secretary Janet Napolitano and FBI Director Robert Mueller are briefing senators now.

We’ll keep you updated on this story as new developments arise.
