Narrative:

Lost right electrical. Restored power with APU electrical (generator). When electrical was restored, lost pressurization. Requested descent. Was given 24000 ft. At 24000 ft ATC would not give us lower. Declared an emergency. Was given lower. Requested a diversion to ord airport. Was denied clearance to ord. This is the reason for the report. I'm on an emergency and yet was denied. (However, they did change their minds and give us clearance to ord.)
