PROVIDENCE, R.I. AP – Two former medical center executives asked a federal appealscourt Wednesday to overturn their convictions for paying a state senator to advance the hospital’s political agenda, saying the trial judge gave the jury flawed instructions.

Robert Urciuoli, the former president and chief executive of Roger Williams Medical Center, was convicted last fall along with former vice president Frances Driscoll for directing ex-state Sen. John Celona to support bills favorable to the hospital and oppose legislation the hospital was against. Their convictions were part of a sweeping federal probe into Statehouse corruption.
