CNN anchor Dana Bash summed up last night's debate between President Donald Trump and Democratic candidate Joe Biden as a "shitshow."

The first debate between Trump and Biden took place Tuesday night at the Cleveland Clinic in Cleveland, Ohio.

Millions tuned in to see whether Biden, 77, would hold his own against 74-year-old Trump, who was predicted to crush Biden in a seemingly one-sided debate.

But the unexpected happened.

In contrast to 2016, when a confident, self-assured Trump stalked debate challenger Hillary Clinton onstage, Trump seemed nervous and anxious at times last night.

Biden was clearly more prepared with his answers to moderator Chris Wallace's questions.

The Fox News host, who is a registered Democrat, faced criticism after the debate for showing favoritism toward Biden.

Wallace, the son of "60 Minutes" icon Mike Wallace, constantly chastised Trump for talking over Biden.

"I guess I'm debating you, not him. But that's okay," Trump told Wallace.

Wallace faced fierce backlash from conservatives and his own colleagues over his apparent bias in favor of Biden.

The numbers don't lie: Wallace interrupted Trump 76 times, while interrupting Biden only 15 times.

At one point, when Trump attacked Biden for criticizing his administration's response to the fading coronavirus pandemic, Wallace jumped in to defend Biden.

Trump slammed Biden for claiming he attended Delaware State University, a historically Black college.

"Did you use the word 'smart?'" Trump asked Biden. "So you said you went to Delaware State, but you forgot the name of your college. You didn't go to Delaware State. You graduated either the lowest or almost the lowest in your class. Don't ever use the word 'smart' with me. Don't ever use that word."

Later, Wallace chided Trump for bringing up Biden's drug-addled son, Hunter Biden. But Wallace was silent as Biden called Trump names such as "clown" and "fool".

During one sequence, Wallace allowed Biden to speak for nearly 2 minutes uninterrupted. But when it was Trump's turn to rebut Biden, Wallace constantly interrupted Trump and wouldn't let him finish.

During another heated exchange between Trump and Wallace, Biden called Trump a "clown" and told him, "shut up, man".

Former journalist Dan Rather called Trump a "bully" for running over Wallace and Biden like road kill.

Actor James Woods tweeted that Wallace was "shamelessly biased".

Fox News host Brian Kilmeade questioned his colleague's bias on Twitter.

"Why is @JoeBiden allowed to interrupt? @realDonaldTrump is not."

And conservative activist Candace Owens questioned why Wallace asked Trump to condemn white supremacists, but didn't ask Biden to condemn Antifa, who are burning down cities and killing people.

Most American viewers were undecided when asked to choose who won last night's debate. But Hispanic Telemundo News viewers were unanimous in their decision.
