The President and other politicians have been targeted for letters containing poison. So too now has a big-city Mayor. Early testing says the poison ricin was sent in anonymous letters to New York City Mayor Michael Bloomberg.

FOX News Radio's Ron Flatter reports from New York:

The letters targeted him and his organization of Mayors Against Illegal Guns.

(Bloomberg) "No, I'm not angry."

New York City Mayor Michael Bloomberg after a laboratory's early read showed the poison ricin was in those letters.

(Bloomberg) "There are people, who I would argue, do things that may be irrational, do things that are wrong."

One letter was opened Friday at a city mail facility. The other Sunday at the DC office of  Bloomberg's gun-control group.

Police say some officers came in contact with the New York letter. No indication of any connection with ricin letters addressed to other politicians, including President Obama.

Read a statement below from the New York City Police Department Deputy Commissioner, Paul J. Browne released Wednesday afternoon:

Anonymous threats to Mayor Michael R. Bloomberg in letters opened in New York City on Friday and by the director of the Mayors Against Illegal Guns in Washington, DC on Sunday contained material that when tested locally, preliminarily indicated the presence of ricin. Tests on the letter opened in New York also preliminarily indicated the presence of ricin in testing today at the National Bioforensic Analysis Center in Maryland. The writer, in letters, threatened Mayor Bloomberg, with references to the debate on gun laws. Civilian personnel in New York and Washington who came in contact with the opened letters remain asymptomatic. However, members of the NYPD Emergency Service Unit who came in contact with the letter that was opened at the city's mail facility on Gold Street in Manhattan on Friday are being examined for minor symptoms of ricin exposure that they experienced on Saturday but which have since abated. The FBI Joint Terrorism Task Force and the NYPD Intelligence Division, which is responsible for the Mayor's protection, are investigating the threats.
