TALLAHASSEE, Fla. (AP) - A federal judge is considering a challenge to a Florida campaign law regulating political committees and similar groups.
    
U.S. District Judge Robert Hinkle heard arguments Wednesday in Tallahassee but did not immediately rule.
    
The law is being challenged by three Sarasota residents backed by the libertarian Institute for Justice.
    
It requires political committees or groups to disclose who made contributions to them, how much and what the money was spent on.
    
The challenge is based on a U.S. Supreme Court ruling that lifted a federal ban on political spending by corporations and labor unions.
    
Hinkle refused to temporarily block the law before last year's election.
    
In that ruling, he said the plaintiffs are unlikely to win because the Supreme Court ruling didn't apply to political committees.
