WASHINGTON (AP) — The White House on Wednesday proposed a new federal rule to limit how law enforcement and state officials collect medical records if they investigate women who flee their home states to seek abortions elsewhere.

The proposal, prompted by a string of blows to abortion across the country, comes as the White House is staring down a legal challenge to a commonly used abortion pill that could upend access to the care across the entire country by Friday.

Vice President Kamala Harris told reporters that it’s one of several new actions the administration is taking to push back against a wave of abortion restrictions that have been introduced since the US Supreme Court overturned the constitutional right to an abortion. The administration is also launching a hotline for people to call and ask questions about prenatal, infant and reproductive care.

“The women in America in particular have been in a state of fear about what this means for them, what this means for the people they love,” Harris said.

The White House’s proposed rule would prohibit health care organisations from sharing personal medical records with authorities for investigations related to reproductive care in states where a woman legally obtained an abortion. While medical records are protected by federal privacy laws, health providers and insurers can be compelled to turn over medical records with a court order.

Doctors around the country have voiced concerns about protecting that medical information from law enforcement officials, said Melanie Fontes Rainer, the director of the office of civil rights at the US Department of Health and Human Services, which proposed the rule change. The public can weigh in on the proposed rule for the next 60 days.

“We’ve had many conversations with providers, major medical associations and patient advocates about what they’re seeing on the ground and how the federal government can be helpful in ensuring medical records are kept private,” she said in a statement.

Since the US Supreme Court overturned the constitutional right to an abortion last year, some women living in a stretch of Southern and Midwestern states that have largely outlawed abortion now travel hours to other states to get abortions legally.

The federal health agency’s new national phone number will provide information about prenatal, infant and abortion care as well as adoption, Health and Human Services Secretary Xavier Becerra announced Wednesday. Becerra did not provide a phone number with his announcement.

The Biden administration is racing to roll out these new initiatives ahead of a pressing deadline imposed by a Texas judge that could revoke the Food and Drug Administration’s approval of mifepristone, one of two drugs used in what is considered the most effective and safest way to carry out a medication abortion.
