US President Donald Trump has lashed out again at NFL players who refuse to stand for the national anthem.
Mr Trump claimed on Twitter that “most of them are unable to define” what they are demonstrating against.
Instead, Mr Trump tweeted that players should “Be happy, be cool!”.
Numerous player demonstrations took place during the national anthem at several early NFL pre-season games on Thursday. Players have been protesting police killings of black men, social injustice and racism.
Mr Trump wrote from his New Jersey golf resort that players “make a fortune doing what they love” and that those who refuse to stand “proudly” for the anthem should be suspended without pay.
Mr Trump has told associates he believes the anthem issue is a winning one that riles up his base.
