On Monday, there was visual evidence of Trump's contempt.
Twice Trump declined to answer reporters' questions on the late senator and, at one point, sat at his desk in the Oval Office, arms crossed and refusing to speak.
Since that momentous political defeat, Trump had, in speeches at rallies across the country, frequently mocked the thumbs-down gesture McCain used to torpedo the legislation.
"I have made mistakes, but I hope my love for America will be weighed favorably against them", he said. John McCain's memorial will be one of the greatest honors he's ever received.
McConnell reflected on the time he was able to spend with McCain this past May at his home in Sedona, Arizona, where he stayed while he underwent treatment for an aggressive form of brain cancer, glioblastoma multiforme.
"What more must my family be put through right now?"
In death, McCain attempted a last word in his farewell letter.

I am just trying to figure out because I saw the reports this weekend that he's traveling with the team. Brady: Yeah, all right, guys. "I'll talk to you later", and hung up the phone.
Trump will not be attending the senator's funeral on Saturday as McCain banned his attendance before his death.
"The damage inflicted by President Trump's naiveté, egotism, false equivalence, and sympathy for autocrats is hard to calculate", McCain said at the time. McCain had been an infuriating foil in a long-running feud over style and policy that did not end with the senator's illness and death.
"Our hearts and prayers are going to the family of Sen". In October 1967, the then US Navy pilot McCain parachuted out of his Skyhawk jet to be taken prisoner and spend more than five years as a prisoner of war.
The blatant disrespect toward McCain drew loud scorn from veterans groups and many others.
Encapsulate the life of a war hero and political giant in only about five or six minutes is something with which Fitzgerald is grappling. He still refuses to call McCain a war hero. Trump appeared to defend the rallygoers when he said there were "fine people on both sides".
Earlier Monday, a statement written by McCain before his death read like a not-so-veiled criticism of the president. 'We weaken it when we hide behind walls, rather than tear them down, when we doubt the power of our ideals, rather than trust them to be the great force for change they have always been'.
At the same time, the White House released a statement from the president in which Trump said that, despite differences on policy and politics, he respects McCain's service to the US and ordered flags be flown at half-staff until his internment.
The flags at the White House were only briefly flown at half-staff to honour Senator John McCain.
