Here is Rudy describing this incident on talk  radio back in July when it first happened courtesy of The Daily Beast:

Speaking to WABC radio that same month, Giuliani admitted that Baron Cohen was trying to capture him in a “compromising” situation. But when he was asked if he did anything that he might be “regretful” about, he replied, “I don’t think so, I’m trying to remember.”

In Giuliani’s telling, he was answering questions on camera from a female reporter when they were abruptly interrupted. “This person comes in yelling and screaming, and I thought this must be a scam or a shakedown, so I reported it to the police. He then ran away,” the former New York City mayor and current personal lawyer for President Trump said. “I only later realized it must have been Sacha Baron Cohen. I thought about all the people he previously fooled and I felt good about myself because he didn’t get me.”

Now, this is how it plays out in the actual movie:

Posing as a conservative journalist in the mold of Tomi Lahren—albeit with a strong eastern European accent—Tutar (The 24-year-old actress who plays Borat’s “daughter.”) sits down with Giuliani in a Manhattan hotel suite for an “interview” in which she mostly flatters him into creepily flirting with her. “I’ll relax you, you want me to ask you a question?” Giuliani says as she giggles in response. After blaming China for the coronavirus, he agrees to “eat a bat” with his interviewer, who repeatedly touches his knee to egg him on.

Baron Cohen first interrupts the interview dressed as a sound engineer with a large boom mic, but leaves before it’s over. At that point, Tutar offers to “have a drink in the bedroom” with Giuliani, who happily obliges.

On what appear to be hidden cameras, we see Giuliani remove her microphone and ask for her phone number and address as he sits down on the bed. He starts patting her backside as she removes the microphone from his pants. Giuliani then lies down on the bed and starts sticking his hands down his pants in a seemingly suggestive manner.

But before anything more can happen, Borat bursts into the room and shouts, “Put down your chram!”—his preferred word for penis. “She’s 15! She’s too old for you!”

The startled Giuliani, who had no reason to believe his interviewer was underage, sits up abruptly and gets out of there as fast as he can. “Rudy, Trump will be disappoint! You are leaving hotel without golden shower!” Borat yells after him.

Currently, that is all we know. Feel free to make your own conclusions.

What we do know is that Sacha Baron Cohen has a unique ability to get conservatives to do the most outlandish things on camera that you can possibly imagine. 

Whether or not he got Rudy Giuliani to polish the bishop on camera I guess we will have to wait until the movie comes out to learn for sure. 

But would I put it past Rudy?
