Yankees players take a knee (screengrab)
President Donald Trump has long complained about players taking a knee before professional sporting events to protest police brutality.
But as Major League Baseball returned on Thursday night, every single player took a knee.
The protesters were started by former San Francisco 49'ers quarterback Colin Kaepernick in 2016.
Before the game, "BLM" was painted on the pitcher's mound to show support for Black Lives Matter.
Both the New York Yankees and Washington Nationals wore "Black Lives Matter" warm-up jerseys.
The first pitch was thrown out by Dr. Tony Fauci, 79, whose pitch was not a strike.
