CHICAGO – Two Chicago congressmen reiterated their support for Jesse Jackson Jr. on Saturday, saying the former Illinois congressman is suffering greatly and needs time to get healthy before he can address the public.

U.S. Reps. Danny Davis and Bobby Rush joined about 200 people for the weekly service at the Rev. Jesse Jackson’s Rainbow PUSH Coalition in Chicago. The service included a special prayer for Jackson Jr. and his family.

The Chicago Democrat resigned from the U.S. House this week, citing his battle with bipolar disorder. He also acknowledged he is the subject of a federal probe and said he’s cooperating with investigators. Federal investigators are reportedly looking into Jackson’s possible misuse of campaign funds. He has not been charged with a crime.
