The bill would prohibit abortions as early as six weeks after conception. Kasich vetoed a similar piece of legislation – House Bill 258, known as the "heartbeat bill" – last month before leaving the office. Kasich is now a CNN contributor.
Legislation has triggered backlash from lawyers for abortion rights. NARAL Pro-Choice Ohio, the State Department of a National Abortion Organization, called the bill "horrible" and "constitutional."
The Republican governor expects that after he signs the bill, he will face litigation the "next day."
"Planned custody will be the next day, or that day, filing a lawsuit, but ultimately this will work up to the US Supreme Court. And they will make that decision," DeWine said.
