In Ohio, Freda J. Levenson, legal director for the Ohio American Civil Liberties Union, said Sunday that her organization and Planned Parenthood of Ohio would file suit early this week to block the implementation of abortion bans in the state, arguing that abortion is a protected right under the Ohio constitution.

The Women’s March, which rallied hundreds of thousands to demonstrations after Donald J. Trump became president in 2017, promised street protests in a “Summer of Rage” and said it would back primary challenges to Democrats it considered complicit in the appointment of the conservative Supreme Court majority.

On Monday, California state lawmakers are expected to put a state constitutional amendment on the ballot that would explicitly protect reproductive rights. In Michigan, where Gov. Gretchen Whitmer has filed suit to stop a nearly century-old ban on abortion from taking effect, activists were collecting signatures on a ballot initiative that would enshrine the right to abortion in the state Constitution.

“We’re going at it, we’re pulling out all the stops,” Ms. Whitmer, a Democrat, said on “Face the Nation With Margaret Brennan.” “This is a fight-like-hell moment.”
