Senator Carl Levin's office evacuated after receiving suspicious letter

Hazmat crews are investigating the suspicious letter received by Sen. Carl Levin's Office.

Outgoing Senator Carl Levin's office in Saginaw was evacuated today after receiving a suspicious letter.

According to Levin's office, a staffer in Saginaw received what they believed to be a "suspicious" piece of mail.

"The letter was not opened, and the staffer followed the proper protocols for the situation, including alerting the authorities, who are now investigating," Sen. Levin said in an email release today.

Police and fire crews are on the scene in Saginaw, according to our sister station, WEYI in Flint.

WEYI says the building has been roped off, though the street is still open. They also say police have entered the building.

Sen. Levin said officials are performing tests on the letter, but they do next expect to have results until late tonight or tomorrow.

The staffer who found the letter is being kept overnight at a local hospital for precautionary reasons, but is not displaying any symptoms, Levin said in a press release.

This is the third report of a suspicious letter being sent to a politician, but there is no word on whether this letter is connected to the two others.

Yesterday, Senator Roger Wicker, of Mississippi, had a letter addressed to his office that was laced with the poision ricin. A suspicious letter intended for President Obama was also intercepted today.

The FBI says those letters are related and are both postmarked out of Memphis, Tenn., dated April 8. Both letters were intercepted at off-site mail facilities.

Levin announced early last month that he will not be seeking re-election in 2014. He is the longest serving senator in state history.
