President Donald Trump on Friday telephoned Cindy McCain, the wife of ailing Sen. John McCain, to extend "best wishes" and see how her husband was doing, the Associated Press reported Saturday.
No other details about the call were disclosed, but on Friday night White House Press Secretary Sarah Sanders tweeted that she was praying for McCain and his family.
"Praying for @SenJohnMcCain, @MeghanMcCain and the rest of his family," she tweeted. "Keep up the fight. America is with you."
Speculation about McCain's health has intensified since the hardworking 81-year-old Arizona Republican began missing Senate votes this week.
McCain's Senate office had said Wednesday that he was hospitalized at Walter Reed National Military Medical Center near Washington, D.C., for "normal side effects of his ongoing cancer therapy." McCain was said to be looking forward "to returning to work as soon as possible," according to a written statement.
The Senate is set to vote next week on landmark tax-reform legislation, but majority Republicans are expected to have enough votes for passage with or without McCain. However, McCain's office has not yet given any indication that he will miss the vote.
He has acknowledged his doctors gave him a "very poor prognosis" and that, in addition to getting treatment, he has been trying to "celebrate, with gratitude, a life well-lived."
McCain started undergoing chemotherapy and radiation treatment in the summer and returned to the Senate after Labor Day and has kept a busy work schedule. But in recent weeks, the treatment has taken a visible, physical toll. He has used a wheelchair on Capitol Hill and has worn a boot on his ankle for a torn Achilles tendon.
His daughter, Meghan McCain, timed her Nov. 21 wedding at the family cabin in Cornville, near Sedona, so that McCain could participate and give away the bride.
