(AP Photo)NEW YORK – Rudy Giuliani is shown in a compromising position in a hotel room with a young woman acting as a television journalist in a scene in Sacha Baron Cohen’s latest mockumentary, a sequel to his hit “Borat” film. Giuliani went to the hotel room thinking he was being interviewed about the Trump administration's COVID-19 response. The young woman is flirtatious with him and invites him to the bedroom, which is rigged with hidden cameras. That leads to a second scheme involving Giuliani that ends up in the hotel room scene.
