Trump attended the NCAA championship football game in Atlanta on Monday, where the Zac Brown Band, accompanied by a gospel choir, performed the anthem.
In recent months, Trump has repeatedly criticized professional football players in the NFL for kneeling during the anthem to protest racial injustice. Three of them carried a sign that said, "The Trump-Pence Machine Must Go". "If you are lucky enough to attend the game, we encourage you to bring a white towel to wave simulating a blizzard while the president is in the packed stadium", the group posted.
The NAACP also planned a "Twitter storm" to begin at 6 p.m. and continue through the game to highlight what they say are lies told by the president. "We respect those who choose to do so, and we fully expect some groups who will be protesting outside the game".
Atlanta's branch of th NCAAP asked protestors to wear white and wave white towels when Trump enters Mercedes-Benz Stadium, with the white referencing the "snowflake" name-calling Trump supporters have used toward his opposers.More news: Trump defends immigration stance in tweet

Atlanta police have said they will set up several designated areas for protesters and won't interfere with demonstrations unless protesters break the law.
In an appearance on MSNBC Sunday, Richard Rose, the president of the Atlanta NAACP chapter, referenced those comments and sent a message to Trump: if Atlanta is "so bad, don't come", he said.
The Federal Aviation Administration banned aircraft including drones from Saturday through Monday night, when the University of Georgia faces the University of Alabama in the College Football Playoff Championship.
Another group, Refuse Fascism ATL, said it was planning a demonstration outside CNN's world headquarters near the stadium.
