Illinois State Police are looking to see if the mayor of Bloomington broke the law when he bought a plane ticket to Japan for his girlfriend. Mayor Tari Renner yesterday said he didn't do anything wrong. Renner said a city worker bought the ticket for a Sister Cities event, where his girlfriend was invited as a delegate, and she reimbursed the city. The Illinois Supreme Court ruled a few years ago that kind of "float" is against the law. State Police investigators aren't commenting on the specifics of the case.
