SAGINAW (WKZO) -- U.S. Senator Carl Levin says tests have shown a suspicious letter sent to his Saginaw office did not contain anything hazardous.
A Michigan Department of Community Health lab in Lansing performed the tests after police were called on Wednesday. One staff member spent a night in a hospital as a precaution.
Levin's office received the letter the same day the White House confirmed someone sent the poison ricin to President Obama.
