The Federal Bureau of Investigation and the United States Postal Inspection Service are investigating a series of "suspicious mailings" sent to state election officials and election offices nationwide, including the Minnesota Secretary of State's Office and U.S. Senator Amy Klobuchar's Minnesota office. 

Threatening letter to MN Secretary of State contained ‘unidentified white powder’
