CORRECTIONS

A Retropolis article in the Feb. 27 Metro section, about former president Jimmy Carter’s mother, incorrectly said Lillian Carter worked as a housekeeper to the Kappa Alpha fraternity at Auburn University. She was the fraternity’s housemother.

A Feb. 26 A-section article about the East Palestine, Ohio, derailment incorrectly said hotbox detectors measure temperature by shooting an infrared beam into bearings on the axles of train cars as they pass over. They detect infrared emissions from the wheel bearings.

A Feb. 26 Metro article about the end of the Virginia General Assembly session incorrectly said the state Senate had balked at including discrimination in a bill that prohibits employers from using nondisclosure agreements or nondisparagement clauses to prevent people from speaking up about sexual harassment. Republicans in the House had objected to the language.

A Feb. 24 Metro article and headline about the nomination of Lt. Col. Roland Butler as superintendent of the Maryland State Police incorrectly said he was acting superintendent upon his nomination to lead the agency. In November, Gov. Larry Hogan selected Butler as acting superintendent effective Jan. 1, but he retired before he could take on that post.
