A former Children’s Hospital of Pennsylvania doctor who sued her employer for pregnancy discrimination—and won—is again suing the hospital and former colleagues for allegedly spreading a rumor that she was a risk to patients.

The defamation lawsuit was filed by Dr. Kaede Ota, who in 2018 entered into a $500,000 settlement with CHOP to resolve claims that her boss, Dr. Robert Doms, discriminated and retaliated against her in connection with her maternity leave.
