PHOENIX - Arizona Sen. John McCain underwent surgery Friday at the Mayo Clinic in Phoenix for a blood clot above his left eye, according to a statement released Saturday by Mayo.

McCain, who turns 81 next month, will be recovering at home in Arizona next week.

With McCain's absence from the Senate, Senate Majority Leader Mitch McConnell announced late Saturday he will delay consideration of controversial GOP legislation that would repeal and replace Obamacare.

McConnell had planned to push the legislation to a vote next week, starting with a motion to proceed to floor debate. But McCain's absence means McConnell wouldn't have enough votes to pass that motion.

Here is the full statement on McCain's surgery from Mayo Clinic doctors:

Following a routine annual physical, Sen. John McCain underwent a procedure to remove a blood clot from above his left eye on Friday, July 14 at Mayo Clinic Hospital in Phoenix. Surgeons successfully removed the 5-cm blood clot (nearly 2 inches) during a minimally invasive craniotomy with an eyebrow incision. Tissue pathology reports are pending within the next several days.

A craniotomy is the surgical removal of part of the bone from the skull to expose the brain.

The Mayo statement goes on:

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. Once the pathology information is available, further care will be discussed between doctors and the family. In the meantime, his Mayo Clinic care team will not be conducting interviews.

McCain's office issued this statement:

Senator McCain received excellent treatment at Mayo Clinic Hospital in Phoenix, and appreciates the tremendous professionalism and care by its doctors and staff. He is in good spirits and recovering comfortably at home with his family. On the advice of his doctors, Senator McCain will be recovering in Arizona next week.

Arizona's junior senator, Republican Jeff Flake, issued this statement:

“I have never known a man more tenacious and resilient than John McCain. I look forward to seeing him back at work soon. In the meantime, Cheryl and I extend our best wishes to John, Cindy and the entire McCain family and pray for his speedy recovery.”

McCain has survived three bouts with skin cancer.

His health came into question during a Senate hearing last month when he appeared confused while questioning former FBI Director James Comey.

McCain blamed it on staying up late the night before to watch an Arizona Diamondbacks baseball game.
