US Sen. McCain doesn't want Trump to attend his funeral

US senator, John McCain (senator representing Arizona) who is currently battling with brain cancer, has reportedly said US president, Donald Trump should stay away from his funeral.

The 81-year-old Vietnam war veteran and 2008 presidential candidate, who has had a rocky relationship with Trump, asked the White House to instead send Vice President Mike Pence reports The New York Times and NBC News reported on Saturday.

I don’t know how much longer I’ll be here, McCain said in an excerpt released last week from his upcoming memoir, “The Restless Wave: Good Times, Just Causes, Great Fights, and other Appreciations.

Maybe I’ll be gone before you hear this,” he said in an audio recording of the excerpt. “My predicament is, well, rather unpredictable. But I’m prepared for either contingency, or at least I’m getting prepared.

The service is planned for Washington’s National Cathedral and will have eulogies read by former Presidents Barack Obama and George W. Bush, a source close to McCain told NBC News.

McCain has been battling an aggressive form of brain cancer since being diagnosed with the disease in July. He is recovering at his Sedona, Arizona, home after undergoing surgery for an intestinal infection last month.

It’s no secret that McCain and Trump have repeatedly butted heads, particularly in recent years.

In 2015, Trump dismissed McCain’s heroism in the Vietnam War, saying he is “not a war hero” because he was “captured.” McCain, a Navy pilot, was repeatedly tortured during the more than five years he was held captive in North Vietnam. He said last fall that Trump never apologized for his insulting remark.

McCain also famously shot down his own party’s attempt to repeal and replace the Affordable Care Act last year. Trump, who had pushed hard for the repeal bill, called McCain’s move “totally unexpected” and “honestly terrible.”
