President Donald Trump has weighed in on the NFL's new rule against US national anthem protests. He said he supports the move, and suggested that players who want to protest the anthem should perhaps leave the US. Trump said: "You have to stand proudly for the National Anthem." Under the new rule, if a player's on the field, they have to stand for the National Anthem. Players have the option to wait in the locker room if they don't want to participate.
