Hear McCain's final statement read by close friend

Sen. John McCain penned a farewell message before he died that appears to take thinly veiled shots at President Donald Trump for fanning the flames of "tribal rivalries" and hiding "behind walls." The moving message, a personal tribute to America and its people, was read to the public Monday by Rick Davis, a close friend of McCain's and the national campaign manager of the Arizona Republican's 2008 and 2000 presidential campaigns.
