2020 presidential candidate Joe Biden conceded it was a "mistake" that millions of people were deported from the United States under the Obama administration.

Biden, 77, addressed the frequently used criticism of his time as vice president during an interview with Univision anchor Jorge Ramos on Friday.

He called the 3 million deportations that took place under the previous administration “a big mistake" and added that "we took too long to get it right.”

“The point is there was too many,” he said. “I saw the pain in the eyes of so many people who saw their families being deported. I know what it’s like to lose family members. It was painful ... It wasn’t until 2012 that we began to get it right with the DACA program and trying very much in 2014 to expand that and moving in the right direction."

The topic of Obama-era deportations has been a question Biden has been forced to answer for at times during the campaign. At September's Democratic primary debate, Biden was addressing the crowd when protesters interrupted him by screaming "3 million deportations!"

At another point in the interview, Ramos confronted Biden about how children caught crossing the southern border illegally were put in cages, albeit at a lower frequency than that of the current administration.
