There has never been any love lost between Donald Trump and Joe Biden.
Neither seems to have any affection for the other at all.
Politicians are often much different in their personal lives than they are when they face the public.

He’s a bad f***ing guy!."
Biden is also quoted in the book discussing Russia’s Vladimir Putin shortly after the Russian invasion of Ukraine.
“That f***ing Putin, Putin is evil.

We are dealing with the epitome of evil.”
Apparently, Joe doesn’t have the calm grandfatherly demeanor people expect behind the scenes.
In fact, there frankly isn’t much the two haven’t said about or called each other.
