U.S. Senator John McCain has requested not to have President Donald Trump attending his funeral. McCain stated that he would much rather have Vice President Mike Pence attending instead.

The 81-year-old Arizona Senator underwent surgery last month for an intestinal infection and has been battling brain cancer for nearly a year. McCain was diagnosed last July with glioblastoma, the same form of brain cancer that killed former United States Vice President, Joe Biden's son, Beau Biden. Senator McCain’s health has been declining ever since his diagnosis.

Joe Biden, traveled to Senator John McCain’s Arizona ranch last Sunday, where the two friends reminisced about senator’s that they worked with and shared moments of laughter together. According to the New York Times, John McCain confided to Biden that he is, “concerned about the state of the country.”

Former Vice President Biden further described his visit to The New York Times saying, “John knows he’s in a very, very, very precarious situation, and yet he’s still concerned about the state of the country.” McCain reportedly told Biden to stay in politics. Biden has been flirting with the idea of running for the 2020 presidential election.

In an audio recording obtained by the HuffPost, McCain states, “My predicament is, well, rather unpredictable.

But I’m prepared for either contingency or at least I’m getting prepared.” McCain has also been saying his farewells just in case of his untimely demise. The Arizona Senator has been reported to have told his son-in-law, Ben Domenech, to “take care” of his daughter. Family and friends of McCain visited the senator where he has been saying his goodbyes.

Donald Trump belittled John McCain's heroic service

In the 2015 primary debate, Trump disregarded McCain’s heroism in the Vietnam War. Trump stated that McCain was “not a war hero” due to the fact that he was captured, stating that a true war hero would have never gotten captured in the first place.

During the Vietnam War, McCain was tortured for more than five years.

Trump’s statement obviously angered McCain and his family. To make the situation worse, Trump never apologized for his insulting remarks on the war hero and veteran.

According to NBC News, Trump physically mocked McCain and blasted him for his “no” vote to repeal Obamacare last summer. On Saturday, The New York Times reported that McCain’s wish is for Trump to stay away from his funeral.

Trump has not made a statement regarding the senator’s wishes.

Who would be attending McCain’s funeral upon his demise?

According to The New York Times, former presidents Barack Obama and George W. Bush will give eulogies at the senator’s funeral. Former presidents and family and friends are most likely to attend.

Senator John McCain’s funeral will be held at the National Cathedral in Washington D.C., sources told NBC.

Meghan McCain stated in a tweet that she is going home to Arizona to be with her family during this most difficult time.
