A number of celebrities have shared their support for NFL players who have taken a knee during the national anthem to protest police brutality against African-Americans, after US President Donald Trump criticised the players and called them "sons of b*****s".

American Football player Colin Kaepernick originally kneeled during the US national anthem before a preseason game last August in protest of the killing of African-Americans by US police officers.

The protest has been gaining steam recently after Trump slammed the players at a rally, saying: "Wouldn't you love to see one of these NFL owners, when somebody disrespects our flag, to say, 'Get that son of a b***h off the field right now. Out! He's fired. He's fired!'"

Trump also shared a number of tweets blasting the NFL players.


NFL athletes have since

, while a number of celebrities have voiced their support, including Gillian Anderson, Zendaya and Olivia Wilde.

Anderson shared a photo of herself and her X-Files costar David Duchovny taking a knee while in character as Agent Fox Mulder and Agent Dana Scully.

Take the knee. Solidarity.
