MADISON, Wis. (AP) — A state senator is promising to update Wisconsin's campaign finance laws in the wake of a number of court rulings. The 7th Circuit Court of Appeals ruled Wednesday that the state's ban on corporate political spending and cap on how much businesses can raise for affiliated political committees are unconstitutional. Earlier this month the state agreed to stop enforcing a cap on individual contributions to candidates to comply with a U.S. Supreme Court ruling. A federal judge in Milwaukee also ruled earlier this month that independent groups that don't disclose their donors can coordinate with candidates. Republican Sen. Mary Lazich says she plans to start working on bills updating the state's laws accordingly this summer for introduction next session.
