Thurman died after waiting 20 hours for emergency care under the state’s abortion ban. Sen. Ron Wyden demanded records his committee could review to determine whether the hospital violated the law. “It’s not even a question,” one expert said.

The Emergency Medical Treatment and Labor Act, or EMTALA, requires hospitals to provide emergency care to stabilize patients who need it — or transfer them to a hospital that can. Passed nearly four decades ago, the law applies to any hospital with an emergency department and that accepts Medicare funding, which includes the one Thurman went to, Piedmont Henry in suburban Atlanta. The finance committee has authority over the regulatory agency that enforces the law.

In a letter sent Monday, Wyden, an Oregon Democrat, cites ProPublica’s investigation into Thurman’s death, which was found preventable by a state committee of maternal health experts. The senator’s letter asks Piedmont CEO David Kent whether the hospital has delayed or denied emergency care to pregnant patients since Georgia’s abortion ban went into effect. (Kent did not respond to requests for comment.)
