CHICAGO — A judge is scheduled to rule on several pretrial motions in the tax-evasion case of an influential Cook County commissioner.

William Beavers' trial begins Monday in U.S. District court in Chicago. The 77-year-old Democrat is accused of diverting campaign funds for personal use without reporting it.

Among the motions Judge James Zagel is expected to rule on Friday is one from the government. It seeks to bar the defense from arguing before jurors that Beavers eventually did pay back all the money at issue. He apparently acted only after realizing he was under investigation.
