Sen. John McCain underwent surgery Friday to remove a blood clot above his left eye, his office and the Mayo Clinic said Saturday, and his weeklong recovery could imperil the vote on the revised healthcare plan in the Senate.
McCain, 80, received the "minimally invasive" procedure following a "routine annual physical" in Phoenix, the Mayo Clinic said in a statement.
"Tissue pathology reports are pending within the next several days," the clinic said.
"The senator is resting comfortably at home and is in good condition," it said. "His Mayo Clinic doctors report that the surgery went 'very well' and he is in good spirits."
The senator's office said in its statement that "on the advice of his doctors, Senator McCain will be recovering in Arizona next week."
A vote that could be scheduled by Senate Majority Leader Mitch McConnell for next week might jeopardize the second version of the Republican's revised bill to repeal and replace Obamacare with McCain in recovery.
So far, two GOP senators – Susan Collins of Maine and Rand Paul of Kentucky – have said they would oppose the revised legislation.
With a slim 52-48 majority, McConnell, who also represents Kentucky, cannot afford to lose more than two votes on the bill.
"Senator McCain received excellent treatment at Mayo Clinic Hospital in Phoenix, and appreciates the tremendous professionalism and care by its doctors and staff," his office said.
"He is in good spirits and recovering comfortably at home with his family."
