Third Letter Sent to President Obama, Similar to NY Mayor Ricin Letters: Sources

A letter was mailed to President Obama that is similar to two letters containing poisonous ricin sent to Mayor Bloomberg and his anti-gun group, law enforcement sources tell NBC 4 New York.

The letter is being tested for ricin. It was received Thursday at an off-site facility, and did not reach the White House, sources said.

The text of that mailing was identical to the letters sent to the mayor and his gun group, which threatened: "what's in this letter is nothing compared to what I've got planned for you," police and law enforcement sources said.

One letter was discovered at City Hall's mail sorting facility at 100 Gold St. on Friday, a law enforcement source told NBC 4 New York. It appeared to contain a pink, oily substance when a mail worker came across it and was immediately flagged as suspicious.
