A group has submitted paperwork to the state attorney general seeking to amend Ohio's constitution to criminalize abortions.
The proposal is the second of its kind nationally. It would "prohibit abortion of all unborn human beings, without exception" and declare the act aggravated murder.
It says it wouldn't affect "genuine contraception," human eggs or in vitro fertilization.
Republican Mike DeWine's office says three people submitted the filing. It was first reported by The Vindicator in Youngstown.
DeWine has until Monday to validate the initial 1,000 signatures and to certify summary language as accurate, fair and truthful. That would advance the proposal to the Ballot Board.
Abortion rights advocates called the measure extreme.
A similar proposal failed to make Oklahoma's 2016 ballot after the state's high court rejected it as unconstitutional.
