Herschel Walker says Donald Trump is RIGHT when it comes to national anthem protests -- saying the NFL needs to impose rules banning players from kneeling during The Star-Spangled Banner. Walker has been a Trump supporter from the beginning -- and while he says they don't agree on everything, he's HAPPY Donald is sticking to his guns on the anthem issue. The ex-NFL superstar says if anyone should fight for Americans to stand up for the flag, it's the President.
