Bob Bashara pleaded not guilty Tuesday at his arraignment on a solicitation of murder charge.
Bashara didn't speak during the hearing. His new attorney, Mark Kriger, stood by his side and entered the plea.
He is due back in court on Aug. 17.
Bashara is accused of trying to have his former handyman Joe Gentz killed while behind bars. Gentz is charged with murder in the death of Bashara's wife, Jane Bashara.
