In this photo taken July 19, 2017, Sen. Jeff Flake, R-Ariz. walks to his seat as he attends a luncheon with other GOP Senators and President Donald Trump at the White House in Washington.  Bombarded by the sharpest attacks yet from fellow Republicans, President Donald Trump on Thursday, Aug. 17, 2017, dug into his defense of racist groups by attacking members of own party and renouncing the rising movement to pull down monuments to Confederate icons.
