Preliminary testing done on a letter mailed to U.S. Senator Carl Levin's office Wednesday has come back with negative results.

The tests were run by the FBI, the Michigan Department of Community Health and a Micro-Biology Laboratory in Lansing.

Levin issued the following statement:

"I have been advised by the FBI that preliminary testing by the Michigan Department of Community Health, Micro-Biology Laboratory in Lansing showed negative results in the suspicious letter received by my Saginaw office.  The office is open as usual this morning.  I want to express my appreciation to the local, state and federal authorities who responded to this incident so quickly and professionally."

A hazardous material team was called to the scene around 11:30 a.m. Wednesday to the office at 515 N. Washington in Saginaw. The building was immediately evacuated. The officer worker who found the letter was transported to a local hospital where he was decontaminated as a precaution.

Levin has offices in Washington and seven in Michigan.
