The Mayo Clinic in Phoenix said in a statement that, following a routine physical, McCain had a procedure to remove a five-centimeter blood clot located above his left eye. A statement from the Mayo Clinic Hospital in Phoenix said the senator is resting at home "in good condition" and that "the surgery went very well".
McConnell's announcement came shortly after McCain's office issued a statement disclosing the surgery and noting that doctors had advised the senator to stay in Arizona next week to recover.
Senators Rand Paul of Kentucky and Susan Collins of ME already announced that they would not support the bill, which the Congressional Budget Office estimated would leave only 22 million Americans without health care, as compared to the 23 million who would lose their benefits under the version passed by the Republicans in the U.S. House of Representatives. He needs 50 of the 52 Republicans and two - Susan Collins, a moderate and Rand Paul, a conservative have already defected.
McCain's sudden absence also shows the fragility of the GOP coalition on health care legislation - one that is supposed to be a hallmark of President Donald Trump's administration to dismantle the Affordable Care Act, or "Obamacare". John McCain is recovering from minor surgery. The removal involved a "minimally invasive craniotomy with an eyebrow incision", the hospital said.

Several other Republicans have expressed concern about the bill including Shelley Moore Capito of West Virginia, Dean Heller of Nevada, Lisa Murkowski of Alaska and Rob Portman of Ohio.
Collins, R-Maine, told ABC News Chief White House Correspondent Jonathan Karl on This Week Sunday that this is because of the bill's extensive cuts to Medicaid.
He knew McCain was not solidly behind the bill.
"So it kind of annoys me that Republicans are going back on their word to repeal Obamacare", he said. If he loses even one more Senator, then it won't matter if McCain is there or not, but with McCain out of town and apparently a "yes" vote for the revised bill, proceeding without him would be fatal for the bill.
"I have never known a man more tenacious and resilient than John McCain", Jeff Flake said.More news: How Dragon Ball FighterZ Could Come to the Nintendo Switch
