Viral Biden-Trump Debate Reactions: Social Media Mocks Presidential Candidates, Celebs Slam Moderators

And while the current president and the former president -- who are presumptive 2024 nominees for the Democratic and Republican parties, respectively -- faced off, social media absolutely went off, with people online taking to X, formerly Twitter, to share their thoughts in real-time.

Many celebrities voiced their frustration online over how CNN moderators Jake Tapper and Dana Bash presided over the debate, claiming they didn't moderate at all. Meanwhile, social media in general poked fun at the whole affair, seemingly viewing the debate as a big, fat joke.

Read on to see how Hollywood reacted to the debate and check out of the best -- and funniest -- viral social media posts.

Celebrities took to X to weigh in on the debate, and a handful of stars called out CNN moderators, claiming they did not fact-check Trump's arguments or make sure he answered the questions.

"whyyyyy moderate if you’re nottttt going to moderateeeeeeee. The lies are rapid fire. CNN wtf?" Glee alum Kevin McHale wrote.

"Trump is a convicted felon - making up whatever he  wants. CNN has abdicated every definitional responsibility," actor John Cusack added, referring to Trump being found guilty of all 34 felony counts in his hush money trial.

"None of us can believe the s--t coming out of Trump's mouth," actress Sophia Bush said. "And I'd wager none of us can fathom why none of the moderators are fact checking Trump's stream of lies?"

Of course, ring-winged celebrities like Caitlyn Jenner and Roseanne Barr showed their support for Trump on X and slammed Biden.

Meanwhile, Jon Stewart -- who is hosting The Daily Show through the 2024 election -- gave his honest analysis of the debate on Thursday's episode of the late-night show, calling out Trump's apparent lies, and Biden's "senior moments."

Towards the end of the segment, Stewart cracked jokes about the pre-debate coverage from Republicans regarding their claims that Biden was given drugs and supplements to help his physical and mental state.

"Let me just say after watching tonight's debate ... both of these men should be using performance-enhancing drugs," Stewart joked. "As much of it as they can get, as many times a day as their bodies will allow."

"Guess what, everybody! They should be taking whatever magical drugs can kick their brains into gear. 'Cause this ain't Olympic swimming ...," he continued, before finishing up his thoughts. "And by the way, if those drugs don't exist -- if there aren't actually performance-enhancing drugs for these candidates -- I could sure f--king use some recreational ones right now because this cannot be real life! It just can't! F--k! We're America! God!"

In his tweet on Friday, Barack Obama first admitted "bad debate nights happen," before continuing to throw support behind his former VP.

"But this election is still a choice between someone who has fought for ordinary folks his entire life and someone who only cares about himself," Obama continued. "Between someone who tells the truth; who knows right from wrong and will give it to the American people straight — and someone who lies through his teeth for his own benefit. Last night didn’t change that, and it's why so much is at stake in November."

Social media users always seem to find the humor in everything, and the debate -- and the overall future fate of America -- was no exception.

Many Americans online clearly weren't thrilled with the current presidential candidates for a multitude of reasons, including the fact that both Biden, 81, and Trump, 78, are the oldest major-party presidential candidates in US history.

They felt the debate, in a nutshell, was a disaster, and reinforced a question many have been asking: Are these really the only two options we have? The best we can do?

"Biden: unintelligible bulls--t, Trump: straight up not-true bulls--t, Moderators: thank you," a user joked.

"ok if you don't live in the US, please turn the debate off," a person said. "this is our private family humiliation, and we'd all prefer you not stare."

"We're cooked," another simply wrote, sharing a graphic that featured the Michael Jordan crying meme over a photo of the United States.

Social media was also full of users cracking jokes about Biden and Trump's ages.

"Making two geriatrics argue in front of the entire country at 9PM is diabolical," a user wrote.

"They shoulda just done hot ones and whoever lived can have it," a second said, while another cracked, "I say give them both a Roku remote and the first one to start a movie gets to be president."

Another person online brought up the recent -- and absolutely hilarious -- Justin Timberlake "Ruin the Tour" meme.

"this is going to ruin the tour," a user joked.
