He is a True Believer, committed to this with everything in him, simply (and I do mean "simply") following the template laid out for them, word for word:
There's always an excuse. Somebody is always corrupt. They're always the victim. It's always a big conspiracy. Someone is always out to get them. The REAL evidence is always being hidden somehow. They are eternally innocent.
Story after story. No matter what.
This is a true, literal, socio-political cult, and he's a prime example of it. Absolutely myopic.
