NEW ORLEANS (AP) — With Aaron Broussard’s corruption trial postponed to Nov. 5, federal prosecutors have moved to delay the sentencing of the former Jefferson Parish president’s ex-wife and co-defendant, Karen Parker. They are seeking an unspecified date in January.

Parker is listed as a prosecution witness against Broussard and co-defendant Tom Wilkinson. Having cooperating witnesses testify against a co-defendant before the witness’ own sentencing is a standard practice with plea agreements such as Parker’s, to help ensure they live up to the terms of their agreements.

Prosecutors say Parker’s attorney does not oppose a delay.

Broussard and Tom Wilkinson, the parish attorney during his administration, have pleaded not guilty to conspiracy, bribery, theft and wire fraud.
