Former Prince George’s County Executive Jack Johnson was indicted Monday on eight federal corruption-related charges, accused of taking hundreds of thousands of dollars worth of bribes during most of his eight-year tenure in a pay-to-play conspiracy involving developers and businessmen.

Johnson, 61, is charged with conspiracy, extortion and bribery as well as tampering with a witness and evidence. The indictment, filed in U.S. District Court in Greenbelt, details seven years of Johnson taking bribes.
