President Donald Trump objected to this action. In 2017, he once called on Americans to boycott a rugby league and culminated in advising the NFL organizers to sack players who rejected American national anthem. “If the players want to make millions of dollars from the NFL, he or she is not allowed to disrespect before the flag and stand when the national anthem plays. If you don’t want to do that, you’re fired. Find another job! ”Mr. Trump wrote on Twitter.
