Last night, in a bipartisan gesture, he was given his award by former Vice President Joe Biden, a longtime Democratic colleague of McCain's in the Senate.
In his remarks, McCain said, 'To fear the world we have organized and led for three-quarters of a century, to abandon the ideals we have advanced around the globe, to refuse the obligations of international leadership and our duty to remain 'the last best hope on earth' for the sake of some half-baked, spurious nationalism cooked up by people who would rather find scapegoats than solve problems is an unpatriotic as an attachment to any other tired dogma of the past that Americans consigned to the ash heap of history.'
The remarks were interpreted as a condemnation of Trump and the forces that got him elected last year.
The president participated in a 'radio row'-type event Tuesday at the White House as a way to sell tax reform.
By the time he talked to WMAL, his fifth interview of the morning, he was in a sparring mood when McCain's comments came up – despite the fact that he'll, again, need the Arizona Republican's vote.
'I hear everything,' Trump said, according to Bloomberg News. 'People have to be careful because at some point I fight back.'
