Nearly all Republican members of Congress, including those from northwestern Illinois, vowed to never raise taxes. On Tuesday, many of them arguably violated their pledge.

Eighty-five of 236 Republicans in the House, including Don Manzullo of Egan and Adam Kinzinger of Channahon, supported the legislation to avoid the fiscal cliff. The measure increased taxes for individuals making more than $400,000 a year and households making more than $450,000 a year.

It was the first time in 20 years that any Republicans in the House or Senate voted for increasing income tax rates.
