Already looking at a possible prison term, former Rep. Jesse Jackson Jr. could face new trouble over his apparent failure to file a financial disclosure report that is required when lawmakers leave the House.

Meantime, his campaign has been warned by the Federal Election Commission about missing recent deadlines for public reports.

Jackson will be sentenced July 1 for misusing more than $750,000 in campaign cash to buy luxury goods and other items. He resigned Nov. 21 and later pleaded guilty to a felony.
