“John McCain was a war hero, should be treated as a war hero, anything less than that is beneath anyone who doesn’t treat him that way. He’s just — he is a hero,” Biden, a 2020 presidential candidate who served with McCain for a number of years in the Senate, told reporters Thursday in Delaware.

“He was a friend of mine. We argued like the devil, as I said in my eulogy, we loved each other, but we argued like the devil. But we abided by the same values, that’s why I love John McCain and that’s why we need a lot more John McCains.”

McCain was held as a prisoner of war for over five years in Vietnam, enduring torture that would permanently impact the mobility in his arms. The Senate Armed Services Committee chairman and former GOP presidential nominee died in August.

Biden’s comments come in the aftermath of reports that military officials sought to hide the USS John S.

Trump and McCain repeatedly clashed, with the president saying McCain was not a war hero and often hitting him over his vote against a GOP plan to repeal ObamaCare.

Questioned about the USS McCain, Trump told reporters Thursday he “was not a big fan of John McCain in any way, shape or form.”

“But I would never do a thing like that,” he added. “Now, somebody did it because they thought I didn’t like him. And they were well-meaning, I will say.”

The Wall Street Journal first reported Wednesday that White House officials requested the ship be "out of sight" when Trump visited Japan over Memorial Day weekend. Measures to hide the ship's name from view were later approved.

The Washington Post and New York Times later confirmed the Journal's reporting, though none of the papers said Trump was involved in making the request. The Journal reported that the U.S. Indo-Pacific Command, the Navy and the White House were involved in discussions.
