Supreme Court Justice Ruth Bader Ginsburg was hospitalized on Tuesday to treat a possible infection.

“Justice Ginsburg was admitted to The Johns Hopkins Hospital in Baltimore, Maryland early this morning for treatment of a possible infection,” spokeswoman Kathleen Arberg said Tuesday.

According to a press release from the court’s press officer, Ginsburg had a fever Monday night before being hospitalized and now the justice is “resting comfortably and will stay in the hospital for a few days to receive intravenous antibiotic treatment.”

In May, Ginsburg underwent endoscopic treatment for a benign gallbladder condition at Johns Hopkins Hospital. She participated in oral arguments from her hospital bed, still recovering from the surgery.

President Donald Trump told reporters Tuesday that he wished her recovery and praised her for “actually giving me some good rulings.”

“I wish her the best. I hope she’s better. I didn’t hear that, actually. She was just hospitalized? No, that’s too bad,” he said. “No, I wish her the best. She’s actually giving me some good rulings.”
