Sen. John McCain underwent a surgical procedure on Friday to remove a blood clot from above his left eye, the Mayo Clinic said in a statement to NBC News on Saturday.
"The Senator is resting comfortably at home and is in good condition. His Mayo Clinic doctors report that the surgery went 'very well' and he is in good spirits," the Mayo Clinic said. "Once the pathology information is available, further care will be discussed between doctors and the family."
McCain, 80, who is chairman of the Senate Armed Services Committee, will be recovering in Arizona next week, his office said in a statement.
Senate Majority Leader Mitch McConnell said he will postpone consideration for the GOP health care bill while McCain recovers.
