President Donald Trump is a "soulless coward," San Antonio Spurs Coach Gregg Popovich told The Nation. Popovich, a vocal critic of the president, called a reporter at the progressive magazine after Trump falsely claimed that President Barack Obama didn't call the families of fallen soldiers. The Spurs coach urged the reporter to let him talk on the record because Trump's remarks about former presidents were "so beyond the pale" that he was nearly speechless. "This man in the Oval Office is a soulless coward who thinks that he can only become large by belittling others," Popovich said. He went on to call Trump a "pathological liar" and said those who work with the president "should be ashamed."

Since last season, primarily black professional football players have knelt during the national anthem before games to protest racial inequality in the United States. The protests started after former San Francisco 49ers quarterback Colin Kaepernick last year began kneeling during the anthem to protest police mistreatment of black Americans. The NFL is slated to discuss the controversy at a meeting this week. In a memo obtained by CNBC, Commissioner Roger Goodell pledged to continue internal dialogue about key issues and said a plan will be reviewed at the meeting. He didn't provide further details on what the proposed plan would entail. White House press secretary Sarah Huckabee Sanders has said the Trump administration "would certainly support the NFL coming out and asking the players to stand" during the national anthem. She said the administration is glad to see the NFL "take positive steps in that direction."
