COLUMBIA, Mo. -- A Republican candidate running for Missouri governor wants to ban abortions that are not medically necessary at or beyond 20 weeks of pregnancy.

Former House speaker and U.S. attorney Catherine Hanaway announced the proposal Tuesday while touring the state.

Missouri currently bans abortions at 20 weeks or later if there's no serious medical risk to the woman. But there's an exception if the fetus is not viable.

Hanaway's proposal would end that exception.

Hanaway also says she wants ramped-up penalties for selling fetal organs. She said she supports defunding Planned Parenthood.

Requests for comment to Planned Parenthood branches in Missouri were not immediately returned.

Hanaway announced the proposals hours before she and four other Republican candidates for governor were set to speak at a forum in Jefferson City.
