“Senator Collins supports the right to an abortion and believes that the protections in the Roe and Casey decisions should be passed into law. She has had some conversations with her colleagues about this and is open to further discussions,” a spokeswoman, Annie Clark, said in an email.

The remarks came hours after the Supreme Court heard oral arguments in a major case that experts believe could lead to the undoing of the landmark 1973 ruling and its precedents that protect a woman’s right to terminate a pregnancy.

But Collins opposes the House-passed Women’s Health Protection Act, which Senate Majority Leader Chuck Schumer, D-N.Y., has promised will get a vote in the Senate.
