Ohio has unveiled new disclosure requirements in response to a U.S. Supreme Court decision earlier this year that eased restrictions on campaign spending.

Corporations, nonprofits and labor groups will have to show the amounts they spend on independent ads for or against candidates, under rules announced Wednesday by Ohio Secretary of State Jennifer Brunner (BROO'-nur).

The state's outgoing elections chief says the ad sponsors also will have to provide voters with a website address in their ads.

The rules include a ban on independent ad spending by businesses that have been awarded state or federal money through Ohio during the previous year.

The rules approved by a Legislative panel give the secretary of state's office the power to pursue violators.
