Carlson, an opinion host on the network, has previously referred to Avenatti as "the creepy porn lawyer." He renewed the tag for his interview to discuss Daniels's lawsuit over a nondisclosure agreement that was used to keep her quiet about an alleged affair with Trump in 2006.

“Creepy porn lawyer, great to see you,” Carlson said as the segment came to a close.

Avenatti slammed Carlson over the on-screen graphics minutes after finishing his appearance on the show.

"After he told me that he was not going to engage in 'name calling.' This is why so many people correctly conclude that @TuckerCarlson is a liar, just like Trump," Avenatti tweeted.

"The extent there was any doubt as to the lack of professionalism of @TuckerCarlson or @FoxNews before tonight, there is no longer," Avenatti continued in another tweet. "What happened with the chyron tonight was a disgrace. Complete garbage - trash television. A new low.

Avenatti's appearance on Carlson's show also comes as he receives more attention surrounding a potential 2020 Democratic presidential bid to challenge Trump.

When Carlson questioned Avenatti about the topic Thursday night, the lawyer noted that the host had asked for him to come on the show to discuss Daniels's case against Trump.
