Transcript for NFL and Facebook reexamine policies in the name of social justice
NFL commissioner Roger Goodell's message to players as a result of their protests. That's as president trump tackles a quarterback for taking back some comments. ABC's Deirdre Bolton has the latest. Reporter: This morning, it's the president versus the NFL again. In a tweet Friday president trump says it was a mistake for New Orleans saints quarterback drew Brees to apologize for his stance against players kneeling in protest against police brutality. I'm a big fan of drew Brees. He should not have taken his original stance back on honoring our magnificent American flag. There are other things you can protest but not our great American flag. No kneeling. The super bowl winning quarterback firing back, writing through my ongoing conversations with friends, teammates and leaders in the black community, I realize this is not an issue about the American flag. It never has been. We can no longer use the flag to turn people away or distract them from the real issues that face our black communities. Brees comments earlier in the week erupted across the sports world leading to a powerful video from numerous players. What would it take for one of us to be murdered by police brutality. Reporter: Roger Goodell changed his stance taking the side of the players. We, the national football league, believe black lives matter. Reporter: Without addressing president trump's comments he delivered a stunning reversal. We the national football league admit we were wrong for not listening to NFL players earlier and encourage all to speak out and peacefully protest. Reporter: Goodell says he has personally protested with those around the country pushing for change and is actively telling players to peacefully do the same. Without black players, there would be no national football league. And the protests around the country are emblematic of the centuries of silence, inequality and oppression of black players, coaches, fans and staff. We are listening. I am listening. Reporter: The commissioner also made no specific reference to former quarterback Colin Kaepernick who began kneeling during the national anthem before games to call attention to racial injustice. The former San Francisco qb has not played in the league for four years with teams refusing to sign him. Believe in something, even if it means sacrificing everything. Reporter: Goodell's statement comes three years after the president first took on the league on a deeply divided issue. Get that son of a Off the field. Reporter: This week, it pledged more than $60 million to causes that fight against systemic racism. Deirdre Bolton, ABC news, new York.
