WASHINGTON (AP) — The medical records of women will be shielded from criminal investigations if they cross state lines to seek an abortion where it is legal, under a new rule that the Biden administration finalized Monday.

The regulation, which is intended to protect women who live in states where abortion is illegal from prosecution, is almost certain to face legal challenges from anti-abortion advocates and criticism from abortion-rights advocates that it does not go far enough.

“No one should have their medical records used against them, their doctor or their loved one just because they sought or received lawful reproductive health care,” Jennifer Klein, the director of the White House Gender Policy Council, told reporters on Monday.

The new regulation is an update to the Health Insurance Portability and Accountability Act of 1996, which prohibits medical providers and health insurers from divulging medical information about patients. Typically, however, law enforcement can access those records for investigations.
