Megyn Kelly has been adamant that she wants to leave her days at Fox News behind, but on Monday morning she resurfaced memories by telling her audience that she complained about Bill O’Reilly’s behavior during her time there — but was ignored.

The reveal came during the monologue of her new NBC morning show, “Megyn Kelly Today.”

Kelly not only went after O’Reilly, but the entire Fox News channel. She claimed that her former bosses and colleagues enabled his behavior and fostered an environment that was toxic to female employees.

The host has said she wants to keep the content of her morning show happy and light, so this was a large departure from her normal programming. Kelly’s show has seen “plummeting” ratings in its first month on-air, leaving many to wonder if NBC will see a return on their reported $69 million investment in the TV host.

Watch her full confession above.
