Rudy was Trump's little mob man. Rudy pulled a lot of strings paving the way for businessman Donald Trump to get away with murder and to engage in some very shady dealings. Not only that, but Rudy also helped Trump avoid taxes and fees and regulations as Trump created his New York empire.
It's all about the money, it always is.
I would bet there is so much crooked shit between Trump and Giuliani, enough to send them both to prison for the rest of their lives. But as we know, rich people get way with pulling this crap all the time and no doubt Donald Trump threatens Rudy Giuliani on a daily basis to force Rudy to fall in line. After all, we know this is how Donald Trump operates. Threats, intimidation, name calling, and more threats. Giuliani wants none of that and so Giuliani falls in line doing whatever Trump demands, even when it makes Giuliani out to be a complete buffoon.
One could almost feel sorry for the guy, Giuliani, given Trump has Rudy by the balls. And it is said that Giuliani cleaned up New York of the filth and smut, but that old Giuliani was the short lived Giuliani. And if one looks closely, I'd bet Giuliani didn't have as much to do with cleaning up New York as Giuliani claims.
Oh.... add into the illusion 9/11, when Giuliani pretended to the world that he was a patriot. That was quite amusing.
