"She was initially evaluated at Sibley Memorial Hospital in Washington, DC, last night after experiencing fever and chills. She underwent an endoscopic procedure at Johns Hopkins this afternoon to clean out a bile duct stent that was placed last August," the Supreme Court statement on the matter read.
"The Justice is resting comfortably and will stay in the hospital for a few days to receive intravenous antibiotic treatment."
The justice went through a "three-week course of stereotactic ablative radiation therapy" as part of her treatment for a cancerous tumor on her pancreas in August 2019.
She also took a hiatus from the Supreme Court in December 2018 to have cancerous nodules removed from her left lung.
