Sen. John McCain, R-Ariz., is receiving treatment at Walter Reed Medical Center in Washington, D.C., for "normal side effects of his ongoing cancer therapy," his office announced Wednesday.
McCain, 81, was diagnosed with an aggressive form of brain cancer called gliolastoma this past summer and underwent surgery in mid-July to remove a 2-inch blood clot in his brain. He rebounded quickly, though, and returned to the Senate on July 25 to a standing ovation from colleagues.
"As ever, he remains grateful to his physicians for their excellent care, and his friends and supporters for their encouragement and good wishes. Senator McCain looks forward to returning to work as soon as possible," McCain's staff said in a statement.
McCain missed votes this week, and the Senate next week is expected to vote on a sweeping tax reform bill.
