Eight years ago, Illinois Rep. Tammy Duckworth used a state-owned vehicle to drive to a campaign event, violating a state law that prohibits government employees from campaigning using taxpayer funds.

At the time, Duckworth was a state employee, the director of the Illinois Department of Veterans Affairs. She had scheduled a day off from her job in order to attend the campaign event, which was being held for then-congressional candidate Dan Seals.
