Gidley replied in a southern twang: 'Very well, thank you,' but Griffin said she didn't believe him.

'Are we really going to do this?' he asked?

Griffin, noted as much for her anti-Trump advocacy as for her near two dozen televised standup comedy shows, went for zero to 60 in a brief second.

'Yes we are,' she yelled. 'Suck my d**k! No, really! Suck my d**k!'

Gidley confirmed the exchange to DailyMail.com. Asked if the 57-year-old Griffin had actually leveled the anatomically impossible epithet at him, he replied: 'Twice.'

Naff wrote that Gidley gave as good as he got, however, detaching from the conversation by saying he planned to enjoy his Mexican beer – a Tecate – 'before we build the wall and you can’t get these anymore.'

President Trump has come under fire from some in Hollywood who see his administration as emblematic of a dying First Amendment

During Monday's broadcast of 'The View,' Griffin retracted her apology for the infamous Trump 'beheading' pictures

Griffin and her husband Randy Bick both came to the White House Correspondents' Association dinner at the Washington Hilton in D.C.

Griffin had the last words: 'F**k you.'

Naff said late Tuesday that he has 'no regrets about inviting Kathy to the Dinner.'

'She's a comic, like Michelle Wolf, and makes her living as a provocateur. I'm far more offended by a president who mocks the disabled, POWs and Gold Star families and who brags about sexually assaulting women.'

On Monday Griffin unleashed an expletive-laden rant against President Trump, and withdrew a previous apology for arranging a photo shoot in which she held a bloody replica of Trump's head.

'Yeah, I take the apology back,' she said on 'The View.'

'F**k him ... and Don Jr. and Eric, or as I call them, "Eddie Munster and Date Rape".'

Griffin said her First Amendment rights were trampled in the resulting negative publicity, likely a reference to CNN's decision to throw her overboard from her annual gig co-hosting its New Year's Eve program.

The First Amendment to the U.S. Constitution prohibits governments from restraining the expression of words and ideas. It does not restrict companies from taking action based on the content of their employees' speech.

Griffin's host on Saturday, Washington Blade editor Kevin Naff, wrote Sunday that during the photo shoot controversy, '[a]ttacking a comedian for doing her job as Trump and his cronies did to Griffin is petty and betrays deep insecurities.' Naff did not respond to an email asking if Griffin did the same thing to Hogan Gidley the night before

At the time Griffin's Trump-decapitation photos caused a national uproar, she fell on her sword as professional bookings began to dry up.

'I sincerely apologize. I am just now seeing the reaction of these images. I'm a comic, I crossed the line... I moved the line, then I crossed it,' she said then.

'I went way too far. The images are too disturbing, I understand how it offends people. It wasn't funny, I get it. I've made a lot of mistakes in my career... I will continue.'

In an essay Sunday that flattered Griffin, Naff opined that the uproar was unfair.

'Attacking a comedian for doing her job as Trump and his cronies did to Griffin is petty and betrays deep insecurities,' he wrote.

Naff disputed that Griffin did the same thing to Gidley on Saturday night, calling the comparison 'off base.'

'Hogan works to defend and justify an administration that attacks everyone from immigrants fleeing persecution to brave transgender service members. If you devote yourself to such cowardice, then you deserve all the heat you get,' he said.
