Obama Receives Another Suspected Ricin-Laced Letter
The letter was postmarked from Shreveport, La., just like the two other ricin-laced letters sent to New York City Mayor Michael Bloomberg and his gun-control group in Washington.

The three officers who came in contact with Bloomberg's letter revealed symptoms of ricin exposure, though no civilian personnel who cam in contact with the letters showed any symptoms.
Both letters that targeted Bloomberg contained an oily pinkish-orange substance, said NYPD Deputy Commissioner Paul J. Browne.
Louisiana State Police spokeswoman Julie Lewis told Fox News that state authorities have deferred to the FBI and have not opened an investigation. The Shreveport postal center handles mail from Louisiana, Texas and Arkansas, so the letter might have come from any of those states, Lewis said.
Last month, authorities arrested a Mississippi man for trying to send ricin-laced letters to the President, a U.S. Senator and a Mississippi judge. His trial is ongoing.
