Kyle Rittenhouse talked about his arrest and trial with Carlson and criticized President Joe Biden for calling him a white supremacist.
"Mr President, if I could tell you one thing, I would tell you to watch the trial and understand the facts before making a statement," Rittenhouse said.
Rittenhouse said it was defaming his character to hear Carlson say it wasn't a small thing to be called a white supremacist.
Carlson and Rittenhouse were referring to a video that Biden posted on his verified account after the 2020 election campaign debate between himself and Donald Trump.
During the debate, Chris Wallace asked Trump if he was willing to condemn white supremacists and militia groups.
While Trump did not condemn white supremacists, he told the members of the Proud Boys to stand back and be ready to defend themselves.
September 30, 2020 is when Joe Biden will post.
The image of Rittenhouse was superimposed over the audio of Trump's response to Wallace's question, which was posted on Biden's account.
Biden said in the video that the President of the United States refused to condemn white supremacists on the debate stage.
