President Donald Trump is being roundly mocked after footage of him singing the national anthem went viral during a college football game in Atlanta on Monday night.

During the Georgia Vs. Alabama game the president took to the field with ROTC members and sang along with the crowd.

But — as with all things Trump — critics lay in wait. Many online took issue with the president’s lip-syncing and apparent mumbling of the song’s lyrics, saying it was evidence that he doesn’t know the words.

“I get it dude. You guys are practically family. I had Roseanne’s back when she f-ed up the National Anthem too,” tweeted Tom Arnold, Roseanne Barr’s ex-husband, in response to a Donald Trump Jr. tweet. (Barr famously butchered the National Anthem at a 1990 San Diego Padres game.)

And it pretty much went from there.

Many online were irate that a president who spent an inordinate amount of time going after NFL players for kneeling during the anthem might be less than familiar with the lyrics of America’s “Star Spangled Banner.” Others argued Obama got unfairly criticized for a much lesser offense: not wearing the traditional American flag on his lapel.

Opinions on Trump’s anthem singing ultimately lay in the eye of the beholder.

Donald Trump doesn’t even KNOW the national anthem after castigating black athletes for kneeling during it! Do you know how much grief Obama would have taken for not knowing these words? The denouncements would gave been deafening… pic.twitter.com/R8OjgdMSPT — Charles M. Blow (@CharlesMBlow) January 9, 2018

TRUMP: “Those ingrate NFL players need to stop disrespecting the… *looks at notes scribbled on hand*… ‘Star Strangled Boner.’” — Jess Dweck (@TheDweck) January 9, 2018

Here is a video of Trump 'singing' the #NationalAnthem.. He clearly doesn't know the words, yet he thinks Colin Kaeprnick is "a son of a bitch" for kneeling during that very anthem.#NationalChampionshippic.twitter.com/s0K8ZJCJdB — Remove Trump Now (@KaniJJackson) January 9, 2018

Trump sings the National Anthem the way everyone sings Bone Thugs n Harmony songs. — Matt Fernandez (@FattMernandez) January 9, 2018

Trump very clearly does not know the words to the national anthem, but please tell me more about how Obama was unpatriotic for not wearing a big enough flag pin pic.twitter.com/yYHjalOECW — Yes, You're Racist (@YesYoureRacist) January 9, 2018

Trump was mouthing some words during parts of the national anthem, but it was unclear what he was saying. He didn't open mouth during other parts. — Josh Dawsey (@jdawsey1) January 9, 2018

Super obvious Trump doesn’t know the words to our National Anthem. Disgraceful for any president, but particularly bad given his months of race-baiting rants against NFL players kneeling to demand justice. pic.twitter.com/jUD0hBqo9N — Kaivan Shroff (@KaivanShroff) January 9, 2018

I bet you all of the immigrants who Trump doesn’t consider to be real Americans know the lyrics to the National Anthem. — OhNoSheTwitnt (@OhNoSheTwitnt) January 9, 2018
