Ohio Gov. Mike DeWine Thursday signed the “Heartbeat bill” into law that will ban abortions once a fetal heartbeat is detected, according to the Associated Press. 

In signing the bill, DeWine broke tradition from his predecessor former Gov. John Kasich who vetoed the bill several times, according to a previous Post report

After the bill was passed Wednesday in the Ohio House and Senate, more than 288 phone calls were received in opposition of the bill and seven in support, according to The Columbus Dispatch.

The American Civil Liberties Union, or ACLU, of Ohio has already filed a lawsuit and said the law is “is a direct violation of the Constitution and a complete undermining of Roe v. Wade,” according to their website.

“This legislation is blatantly unconstitutional and we will fight to the bitter end to ensure that this bill is permanently blocked,” said Freda Levenson, legal director at the ACLU Of Ohio in a media release. “SB 23 is one of the most aggressive, oppressive, and radical attacks against women ever seen in this state and this country.”
