Several mainstream media outlets are reporting that the FBI and Secret Service have intercepted a suspicious package, or envelope, intended for President Barack Obama.
MSNBC is reporting that the package has initially tested positive for ricin, an organically derived protein that can be fatal if inhaled, even in miniscule quantities.
The parcel was intercepted at an off-site screening facility for mail addressed to the White House. Investigators believe they know the source of the mailing, but haven’t made any arrests.
Reports of parcels targeting Obama, as well as U.S. Senators Roger Wicker (R-Miss.) and Richard Shelby (R-Ala.), are mounting since Monday’s bombing at the Boston Marathon. The FBI, which has taken over that investigation as well, currently isn’t linking the bombing with the targeting of Washington politicians.
