The former Democratic congressman from Illinois and his wife could be sent to prison. He pleaded guilty to misusing $750,000 in campaign money. She admitted failing to report to the Internal Revenue Service about $600,000 of their income.

"A new date for both of the Jacksons will be set later," he said
