A political committee leading efforts to pass a ballot proposal on abortion rights filed a federal lawsuit Wednesday alleging the state violated the First Amendment by threatening television stations over an ad supporting the measure.

A group campaigning for a Florida abortion-rights measure is suing state officials over their order to TV stations to stop airing one ad.

A group of anti-abortion advocates are trying to force Florida’s abortion amendment off the ballot this November or void any votes cast for it, citing a report from the DeSantis administration that said there was “widespread” fraud in the petition gathering for the effort.
