One of the Chicago area’s most visible immigrant leaders is planning to challenge Congressman Dan Lipinski in this winter’s Democratic primary.

Illinois’s 3rd Congressional District includes parts of Chicago’s Southwest Side and some nearby suburbs. Many Latin Americans and Middle Easterners have been settling there.

Jorge Mújica of Berwyn says Congressman Dan Lipinski isn’t representing them well.

MUJICA: He’s consistently voting against any kind of legislation that could benefit these immigrants.

Mújica has helped organize huge immigrant rights marches through downtown Chicago. He’s gathering signatures to get on the February ballot.

Lipinski’s campaign Wednesday didn’t return our calls. The congressman holds a distinct advantage. He reported more than $450,000 in campaign funds on hand as of June 30.
