BOSTON (AP) — U.S. Sen. Elizabeth Warren on Wednesday warned about additional attempts to curb access to abortion — efforts that she said could ultimately target states like Massachusetts that have worked to protect abortion rights.

Warren held a field hearing in Boston along with fellow Democratic Sen. Edward Markey, also of Massachusetts, to highlight some of those concerns following the decision by the U.S. Supreme Court in 2022 to overturn Roe v. Wade.

Even in states that have tried to enshrine abortion rights — in 2022, Massachusetts lawmakers passed a shield law designed to protect abortion providers from out-of-state legal actions when they provide care to people living in states with abortion bans — further restrictions loom, Warren said.

“I’m furious that millions of women have lost fundamental rights. I’m furious that their freedom to make their own decisions has been taken away by a small number of extremists,” Warren said, adding that she’s even more concerned about what could happen if Donald Trump wins back the White House.
