Trump told reporters on Sunday that he spoke to McCain's wife, Cindy, and wished the couple well.
The already narrow margin for the tax reform bill is exacerbated by concerns for McCain's health, and the health of another member, GOP Sen. He did so as an insurance policy for McCain's absence, two Republicans close to the matter said.
Republican Sen. John McCain left Washington, D.C., Sunday to be with his family in Arizona, and will miss the vote on the Tax Cuts and Jobs Act expected this week, CBS News reports.
"I'm happy to say that he's doing well", said Domenech, a conservative writer. "The truth is that as anyone knows whose family has battled cancer or any significant disease that oftentimes there are side effects of treatment that you have", he said. He received a diagnosis early this year of glioblastoma, an aggressive, malignant brain tumor that can cause headaches, seizures, blurred vision and other symptoms.
Trump said: "He's going through a very tough time, there's no question about it". "But he will come back if we need his vote". Vice President Mike Pence can also cast a tie-breaking vote, should it come to that.
However, republicans appear to still have the votes necessary to pass the sweeping bill. McCain was one of only three GOP senators to vote against the measure, which came in dramatic fashion in the early morning hours. Bob Corcker and Marco Rubio after they had originally opposed the Senate's plan.
As a Navy pilot, McCain lived through a July 1967 fire that killed 134 sailors aboard the aircraft carrier USS Forrestal in the Gulf of Tonkin during the Vietnam War.
