Former Congressman Jesse Jackson Jr can still collect an annual pension even though he is under a federal investigation.
Jackson resigned from Congress, after 17 years of serving a district in the south side of Chicago, just before Thanksgiving.
In his resignation letter, Jackson acknowledged that he was the subject of an investigation and that he had made some mistakes.
Earlier this year, Congress expanded the number of felony public corruption offenses that could take a federal pension away.
They include tax evasion, money laundering, and offenses relating to soliciting political contributions.
A federal criminal investigation is looking into whether Jackson spent campaign money on furnishing his home in Washington and an expensive watch for a female friend.
Jackson stands to lose his federal pension if he is convicted of one of several public corruption felonies.
Right now, Jackson is not charged with a crime.
The National Taxpayers Union estimates that Jackson, who is now 47, could collect $45,000 a year when he turns 62.
Jackson has stayed out of the public since he went on medical leave in June.
He has been in and out of treatment for bipolar disorder, at the Mayo clinic.
