That Hannity didn't believe Sidney Powell's nonsense isn't surprising; it was baseless garbage from the jump.

But that he hosted her anyway, even after Fox itself had kneecapped her, is a reflection of how toxic the network really can be. https://www.washingtonpost.com/politics/2022/12/22/fox-news-hannity-trump-2020-election/

Why Sean Hannity’s dishonesty matters

The Fox News host reportedly admitted he elevated false claims he didn't believe after the 2020 election. His was the most-watched show on cable news that year.

@pbump At the same news conference where Powell gave her deranged presentation was Joe DiGenova, the former U.S. Attorney for the District of Columbia who was named “Independent Counsel” in connection with Bush 41’s rifling of Clinton’s State Department passport file by the Bush campaign. It was a preview of what Trump tried with Zalenskyy re: Hunter Biden. Joe DiGenova declared it was no big deal and closed the file.
