Just one day after a sober televised address on Afghanistan, President Trump returned to attack mode, waging an all-out assault on his critics during a campaign rally in Arizona. Addressing thousands of supporters in Phoenix, Trump went on offense during a 77-minute airing of grievances against his political opponents, while protesters gathered outside. The commander in chief criticized a war hero with brain cancer and a senator from his own party facing re-election next year on their home turf.
