Supreme Court Justice Ruth Bader Ginsburg is "resting comfortably" and is expected to remain hospitalized for a few days following lung surgery on Friday, court officials said in a statement. She underwent a pulmonary lobectomy at New York City's Memorial Sloan Kettering Cancer Center to remove two malignant nodules from her left lung, the statement said. Scans before the surgery found no disease elsewhere in her body, there was no evidence of remaining disease after the procedure, and no further treatment is currently planned, according to the statement.
