Especially for the guy who knows more about everything than everyone.That's his go-to defense mechanism when cornered. He doesn't know that person, he doesn't know anything about that group, he doesn't know anything about what you're talking about.

He just lies and lies and lies, and his enablers just keep enabling it.
The MAGAts must really want to own libs. What did you do to them, hold up a mirror to them or something?
