when Donald Trump and Rudy Giuliani are cell-mates, how will they affect or organize the prison system?

Organize? Neither one has organized anything in their lives, which are constant chaos.

They'll build smuggling tunnels under the floor so that Trump can get his Big Macs and fries.

Now that's a thought. the two of them as cell mates. Imagine that...

They'll do what they did during the last years of their political career. Say and do things that appeal to the lowest of the white supremacist inmates, and organize them with Trump as their de facto leader, all the while claiming not to be racist.
