WATCH: Joe Biden mixes up Jacob Blake and Kyle Rittenhouse, lies about Trump

On a live segment with CNN, Anderson Cooper asked Biden for his thoughts on why President Donald Trump has not yet mentioned the shooting of Jacob Blake, to which Biden responded: "I don't know enough to know whether that 17-year-old kid, exactly what he did, but allegedly he's part of a militia coming out of Illinois."

Biden continued: "Have you ever heard this president say one negative thing about white supremacists?"

To this, Biden spread the lie that Trump called the white supremacists at Charlottesville "very fine people," rather than condemning them.

In reality, the transcript of Trump's press conference actually paints a much different picture.

Trump: Excuse me, excuse me. They didn’t put themselves -- and you had some very bad people in that group, but you also had people that were very fine people, on both sides. You had people in that group. Excuse me, excuse me. I saw the same pictures as you did. You had people in that group that were there to protest the taking down of, to them, a very, very important statue and the renaming of a park from Robert E. Lee to another name.

Reporter: George Washington and Robert E. Lee are not the same.

Trump: George Washington was a slave owner. Was George Washington a slave owner? So will George Washington now lose his status? Are we going to take down -- excuse me, are we going to take down statues to George Washington? How about Thomas Jefferson? What do you think of Thomas Jefferson? You like him?

Reporter: I do love Thomas Jefferson.

Trump: Okay, good. Are we going to take down the statue? Because he was a major slave owner. Now, are we going to take down his statue?

So you know what, it’s fine. You’re changing history. You’re changing culture. And you had people -- and I’m not talking about the neo-Nazis and the white nationalists -- because they should be condemned totally. But you had many people in that group other than neo-Nazis and white nationalists. Okay? And the press has treated them absolutely unfairly.

Now, in the other group also, you had some fine people. But you also had troublemakers, and you see them come with the black outfits and with the helmets, and with the baseball bats. You had a lot of bad people in the other group."

Biden also forgot how many grandchildren he had

During another recent interview—this time, with rapper Cardi B—Biden said that he had "four kids,"and "five grandkids."

Biden, whose cognitive abilities have been called into question by President Trump, actually has seven grandchildren: Natalie, Robert, Naomi, Finnegan, Maisy, and a seventh child whose name is not public.

The former vice president has come under some scrutiny as compilations of gaffes continue to weigh the now 77-year-old Biden down.

During Fox News town hall, Trump implied that Biden had memory problems after Biden said that he was running for Senate, and that 150 million people were killed by guns in the United States, saying "there's something going on there."
