Giuliani was slated to appear on “Fox & Friends” to mark the 20th anniversary of the attack. But the night before, host PETE HEGSETH called Giuliani to say he’d been cut from the show and apologize.

The ban extends not just to GIULIANI, but also to his son ANDREW, who has not been on Fox News since he launched his campaign for governor of New York in May despite many requests to go on the network. His team has been frustrated that rival GOP gubernatorial candidate Rep. LEE ZELDIN is a frequent guest.

But bookers have told both Giulianis the ban comes from the top, sources said. The former New York City mayor had been a fixture on the network.

“Rudy is really hurt because he did a big favor for RUPERT [MURDOCH],” a source close to Giuliani said. “He was instrumental in getting Fox on Time Warner so it could be watched in New York City.” In 1996, Giuliani’s administration advocated for Time Warner to carry the newly launched Fox News Channel, intervening in a dispute between Murdoch and the cable provider.
