CLEVELAND — The bribery trial of a county commissioner in Cleveland won’t begin until after he leaves office in January.

A federal judge set a Sept. 12 trial date on today for Cuyahoga County Commissioner Jimmy Dimora and five co-defendants. They include a judge running for re-election next month.

All have pleaded not guilty and are among more than three dozen people charged in a two-year FBI investigation of alleged public corruption. Many charges allege bribes were paid in return for jobs and contracts.

Attorneys in the Dimora case described a complex case that includes thousands of hours of wiretaps and perhaps hundreds of thousands of documents.

The wrongdoing alleged by investigators spurred voters to change the county government — effective next year — from three commissioners to a county executive and county council.
