Former Congressman Jesse Jackson Jr. might still be able to collect $45,000 a year in federal retirement benefits.
He would lose the pension, however, if he's convicted of one of several public corruption felonies.
The Chicago Democrat resigned from his U.S. House seat last week, citing his battle with bipolar disorder. He also acknowledged he is under federal investigation, though he has not been charged.
The Chicago Tribune reports that Pete Sepp of the National Taxpayers Union estimates Jackson could collect $45,000 a year when he reaches age 62.
Congress has expanded the list of felony public corruption offenses that would result in the loss of a pension. Among those offenses added to the list are tax evasion, money laundering and offenses relating to soliciting political contributions.
