The debate between former President Donald Trump and Vice President Kamala Harris was full of viral moments, for many different reasons. 

According to the Daily Mail, Trump made one of those viral moments by invoking something Harris famously said during a debate in 2020 when she was running for president before ultimately dropping out before the first vote was cast.

Trump and Harris traded several barbs throughout the night, with Trump continually attacking Harris on issues like the southern U.S. border and the fledgling economy.

Opinions regarding who won the debate, for the most part, broke down along party lines. Harris supporters believe she clearly won, while Trump's supporters thought he won, especially given that he appeared to be debating not only Harris, but the two ABC moderators.

What did he say?

One of Trump's best moments of the night is when he used one of Harris' own lines against her as she attempted to interrupt him, but failed because her microphone was off.

At one point, Harris tried to cut in on Trump's talking time after he said she was all about defunding the police. Viewers could see her mouthing something but couldn't hear it because her mic was off.

"Wait a minute, I'm talking now," Trump said. "If you don't mind, please."

"Does that sound familiar?" Trump added, invoking the same line she used against former Vice President Mike Pence during the vice presidential debate in 2020.

BREAKING: Trump just did the most SAVAGE thing ever. He was talking, and Kamala Harris tried to interrupt, and he said, "Wait a minute, I'M TALKING NOW!"

Clearly, Harris wasn't happy about the moment, as it made her look foolish.

Social media reacts

Trump's supporters on social media applauded the former president for turning her own line against her in a key moment during the debate.

"Highlight of the night. I was so proud. Excuse me I'm talking now. Sound familiar. He was such a gangster in that moment," one X user wrote.

Another X user wrote, "The look on her face makes me hate her, she is like the mean girl in school."

It'll be interesting to see which of the candidates receives the biggest boost from their debate performances.
