The U.S. Postal Inspection Service has launched after all 25 Republicans in the Ohio state Senate were mailed "envelopes full of feces," The Columbus Dispatch reported Thursday.

"The packages arrived after being sent almost a week earlier from a Cleveland post office," the newspaper reported. "The packages were intercepted by Statehouse, Cleveland and Akron post offices before reaching the senators, according to a statement from Ohio House spokesman John Fortney."
