McCain returning to Arizona to start cancer treatment Monday

Sen. John McCainJohn Sidney McCainSylvester Stallone reportedly joins Trump's Mar-a-Lago The Hill's 12:30 Report: Biden meets with bipartisan lawmakers for infrastructure negotiations Cindy McCain to be named Biden ambassador to UN program: report MORE will return to Arizona to start cancer treatment next week.

“In accordance with the guidance of his physicians, Senator McCain is returning to Arizona to undergo further treatment at Mayo Clinic,” his office said on Friday. 


They added that McCain will “begin a standard post-surgical regimen of targeted radiation and chemotherapy” on Monday.

McCain returned to the Senate on Tuesday, after his office announced last week that he had been diagnosed with brain cancer.

In a floor speech, McCain said that he would only be around the Senate for a “few days” before he would return to Arizona to start cancer treatment.

“I’m going home for a while to treat my illness. I have every intention of returning here and giving many of you cause to regret all the nice things you said about me. And I hope to impress on you again that it is an honor to serve the American people in your company,” he said from the Senate floor on Tuesday.

McCain's office added on Friday that the 80-year-old senator “will maintain a work schedule” during his treatment, and “plans to return to Washington at the conclusion of the August recess.”

If senators stick to their current schedule they will be in Washington until mid-August, when they will leave town until early September.  

McCain had hoped the Senate could take up the National Defense Authorization Act before he had to leave Washington again, but Sen. Rand PaulRandal (Rand) Howard PaulCharles Booker launches exploratory committee to consider challenge to Rand Paul Rand Paul calls Fauci a 'petty tyrant' Biden picks vocal Trump critics to lead immigration agencies MORE (R-Ky.) blocked an effort to bring up the bill.

"Senator Rand Paul requested two bipartisan amendments, one on ending indefinite detention and one on [authorizations for use of military force]. He looks forward to working with leadership and the committee to get this done soon," said Sergio Gor, a spokesman for Paul, when asked about the objection.

McCain countered on Friday that "it is unfortunate that one senator chose to block consideration of a bill our nation needs right now, the National Defense Authorization."
