John McCain ’s ‘ Why Courage Matters.’ Khan said he has long respected the Arizona Republican , and that one of his last conversations with his son had been about the book and McCain ’s sacrifice … McCain had been ‘ my and my family ’s hero,’ whom Khan said they admired as someone who ‘ gave so much in care of others.’ ... It ’s that admiration that led Khan to call on McCain and other GOP leaders to withdraw their support of Trump : ‘ I implore Sen. McCain … this will be a historic moment in the Republican Party,’ Khan said during an interview with Cronkite News . ‘ If you publicly rebuked him , you will look back and you will stand tall in front of the nation and you will say you were not for this , we were for [ a ] better America,’ he said .
