On Tuesday night, in the first presidential debate of the 2020 race, Republican President Donald Trump and Democratic nominee Joe Biden often engaged in chaotic changes.

The two candidates frequently launched harsh personal attacks towards each other. There were several quotes that drew traction on social media.

“You’re the worst president in the history of the United States,” Biden said.

“I’ve done more in 47 months than you had done in 47 years,” Trump jabbed at Biden, referring to his long political career.

“It’s hard to get any word in with this clown,” Biden said while sparring with Trump over his son Hunter Biden. Trump claimed Biden’s son had profited from his tenure as vice president in the Obama administration.

On racial justice, Biden said Trump frequently used racist dog whistles. In response, Trump falsely claimed Biden had referred to the Black community as “super predators.” As Mother Jones noted, the phrase "super predators" was used in 1996 when Hillary Clinton referenced drug gangs.

On violence, Trump accused Biden of supporting rioting in American cities.

"Do you believe in law and order?" Trump asked Biden.

"Law and order with justice where people are treated fairly,” Biden responded.

The two candidates also discussed the COVID-19 pandemic, the Affordable Care Act, and Trump Supreme Court nominee Amy Coney Barrett.

“You should get out of your bunker and get out of the sand trap and ... the golf course and go in the Oval Office and [put]together Democrats and Republicans, and fund what needs to be done now to save lives," Biden said.

“You didn’t think we should’ve closed our country [to China] because you thought it was terrible," Trump said.

One of the most notable quotes came from Trump when asked about condemning white supremacy.

"Proud Boys, stand back and stand by! But I'll tell you what, somebody's got to do something about antifa and the left," Trump said.

Megan Squire, a professor of computer science at Elon (N.C.) University who studies online extremism, told USA Today the group “reacted exactly as I thought they would. They were extremely excited by what he said. They felt validated. They took it the same way everybody listening took it — that he was giving them a shout-out, basically.”

NBC News' "Meet the Press" moderator described the debate as a "train wreck." "Today" show anchor called the debate "undignified" and "cringe-worthy." ABC News chief global affairs correspondent Martha Raddatz said, "It was not a presidential debate. It was mud wrestling."

There were also several notable tweets.
