McCain vows to be back following cancer diagnosis

WASHINGTON — Battling brain cancer, John McCain on Thursday vowed to return to the Senate, levelling fresh criticism at the Trump administration and aiming a good-natured dig at Republican and Democratic colleagues shaken by news of his diagnosis.

“I greatly appreciate the outpouring of support — unfortunately for my sparring partners in Congress, I’ll be back soon, so stand-by!” McCain said in a tweet. Showing no signs of stepping back from political and national security battles, he issued a statement slamming the Trump administration over its Syria policy.

The 80-year-old McCain, the GOP’s presidential nominee in 2008 and a six-term Arizona lawmaker, was diagnosed with glioblastoma, an aggressive type of brain cancer, according to doctors at the Mayo Clinic in Phoenix, who had removed a blood clot above his left eye last Friday. They also managed to remove all of the tumour that was visible on brain scans.

The senator and his family are considering further treatment, including chemotherapy and radiation, as he recuperates at his home in Arizona. President Donald Trump called the senator on Thursday, said a White House official who spoke on condition of anonymity to discuss private talks.

In a blistering statement through his office, McCain criticized the administration over reports that it was ending a program to assist Syrian opposition forces fighting the government of Bashar Assad.

“If these reports are true, the administration is playing right into the hands of Vladimir Putin,” said McCain, chairman of the Senate Armed Services Committee. “Making any concession to Russia, absent a broader strategy for Syria, is irresponsible and short-sighted.”

More significantly, McCain’s absence complicated Republican leader Mitch McConnell’s plans for a Senate vote on a GOP health care bill to erase much of Barack Obama’s law. A vote is possible as early as Tuesday, but Republican defections plus McCain’s likely absence could sink any chance even to get started.

McCain’s closest friend in the Senate, Lindsey Graham of South Carolina, said that they had spoken by telephone Wednesday night and that the diagnosis had been a shock to McCain.

It was unclear how long McCain might be out.
