Donald Trump told two lies when tweeting about NFL players who protested racial injustice by kneeling or raising a fist during the national anthem during Thursday's slate of preseason games.
Trump claimed that "most of them are unable to define" what it is that they are protesting against, but that is incorrect. Since former quarterback Colin Kaepernick first started the protest in 2016, he made it very clear that he was protesting against racial injustice, systematic inequality, police brutality and general racial oppression in the United States. Since then, the other players who have made some sort of demonstration during the national anthem have echoed that sentiment and repeatedly asked for the issues they are protesting against to be the focal point of the discussion, instead of talking about the way in which they are protesting.
