One of Illinois' congressmen is being called one of the most corrupt in Washington. A Democratic leaning organization says Chicago Republican Joe Walsh is a "deadbeat dad" who cares about his own ambitions more than he cares about his children. Walsh is in a child support battle with his ex-wife. She claims the politician is more than 100-thousand dollars behind in child-support payments, an accusation that Walsh denies. The Citizens for Responsibility and Ethics in Washington names who they call the most unethical politicians in an annual report. Walsh isn't the only Illinoisan to make the list. Former U.S Senator Roland Burris and Congressman Jesse Jackson, Junior both made the list two years ago.
