Carlson slammed the network and its on-air personalities for spreading dangerous rhetoric.
Carlson told CNN's Jim Acosta that conservative television news is not the same as it was five years ago.
Carlson said that conservative media had moved into eliminating any other point of view.
She said that it had gone from an opinion to completely devolving into non-fact-based conspiracy theories.
A Fox News spokesman did not immediately respond to Insider's request for comment on Sunday.
Several top Fox News anchors, including Sean Hannity and Laura Ingraham, were in contact with the team of former President Donald Trump during the riot at the US Capitol on January 6, 2021, asking him to tell his supporters to leave the grounds.
The on-air personalities took a different stance on the insurrection, suggesting that groups like Antifa were responsible for the riot.
It is possible that media figures on both sides of the political aisle have advised the White House, but still condemned the actions of her former colleagues.
I think the bigger story coming out of that is how disingenuous it was to be sending those texts of warning while then going on the air to the American people and doing a complete injustice and disservice by saying something completely opposite.
Carlson, who worked at Fox News for a decade from 2006 to 2016, said there was a big difference between having conservative opinions and supporting conspiracy theories.
Carlson settled a sexual-harassment lawsuit against Roger Ailes, the network's former chairman and CEO, for $20 million. A dozen other women have come forward and accused Ailes of sexual harassment, including Megyn Kelly.
Carlson said that he wished more of them would come forward and take on a giant.
