Donald Trump has drawn the battle lines ... if the NFL allows players to take a knee during the national anthem in 2020, POTUS says his days watching pro football are over!
President Trump made his threat during a Friday morning tweet that initially took aim at Dr. Anthony Fauci.
Remember, earlier this week Fauci warned America that a second wave of COVID-19 could impact pro sports -- and said straight-up, "Football may not happen this year."
"It would be very hard to see how football is able to be played this fall," Fauci told CNN.
