As questions continue about Rep. Jesse Jackson Jr.'s future, his congressional staff was expecting an update this morning via conference call. However, Chicago's CBS affiliate WBBM reports the call, which Jackson was reportedly supposed to lead, was cancelled just as fast as it was scheduled, leaving staffers with no explanation.

According to Fox 32 in Chicago, Jackson, an Illinois Democrat, had planned to take part in "a conference call at both his Washington D.C. and Chicago offices with some workers, while others will receive an e-mail about his future plans in politics -- and possibly the details of his plea bargain with the federal government."

"There was a conference call. I was informed the congressman was going to have a conference call with the staff at 10 a.m.," Jackson spokesman Frank Watkins told the Chicago Sun-Times Tuesday night.

But a few hours later, the call was called off.

Jackson won reelection to his Chicago-based district on Election Day but has not made a public appearance nor returned to his office on Capitol Hill. Questions continue to swirl about his whereabouts and his plans for the future.

In addition, Jackson is being investigated for misusing campaign funds. His attorney is reportedly involved in discussions for a plea deal that would involve him stepping down from Congress and serving jail time but allowing him to keep his federal pension.
