Before Alabama and Georgia played the NCAA Football National Championship game, the Zac Brown Band took the field to sing the national anthem.
Before heading to the college national football championship on Monday, President Trump reiterated his views on athletes using the national anthem to protest racial discrimination and police violence in America.
"Trump doesn't know the national anthem".
"IDEA: Before spending 6 months lecturing football players about respecting the national anthem MAYBE LEARN THE WORDS", tweeted Judd Legum, editor of the lefty news outlet ThinkProgress.
During one of his speeches, Trump even called a football player who refused to stand at attention during the performance of the United States national anthem "son of a bitch".
Trump began singing along from the very beginning of the song, but only mouthed a few words here and there.
Trump, who has made a respectful observation of the national anthem at sporting events a fiercely divisive political issue, stood at midfield and sang some of the "Star-Spangled Banner," while remaining silent at other times.
"There's plenty of space for people to express their views and to protest, but we love our flag and we love our anthem, and we want to keep it that way", he said.
Even if the President doesn't know every word to the National Anthem, it shouldn't actually be a huge deal - a song recitation shouldn't be a prerequisite for the presidency. He renewed the attack earlier Monday on Twitter.
Video of the performance shows Trump mouthing some of the words, but he also appeared to have botched some of the lyrics.
The White House did not respond to a request for comment.
Some Twitter users cried hypocrisy against Trump for his tweets against players taking a knee and Colin Kaepernick but found it totally ridiculous when it appeared that Trump was rambling his way through "The Star-Spangled Banner".
