I don't think your conspiracy is very clear at all. So the FBI are the ones that lied and didn't tell Mueller, but once Brandon got the right people at the FBI, they did told Durham?
Or the FBI told both, and both of them sit on it for a long ass time? Which one is it?
We're going in circles. Steele/Sussman/Danchenko (and Clinton) were not part of any investigation at the time. Again, the allegations at the time were that the Trump campaign colluded with Russia, which was reinforced after it was known that Flynn lied to the VP about talking to the Russian ambassador.
Mueller and Durham are not investigating the same thing either. I have zero problem with Durham's investigation, and I'll read his conclusions whenever they come up or when he speaks (just like I did with Mueller).
The problem I see here are useful idiots that try to spread fake news to establish a narrative by consistently jumping to conclusions that end up making them look stupid. Happened with the Mueller report, happened with the OIG report, happened with GUCCIFER 2.0, happened with Pizzagate, etc, etc, etc
People with room temperate IQ and above generally realize they've been used as fools, take a step back and use some critical thinking to avoid falling for the same thing over and over again. But if you enjoy constant embarrassment, I'm not going to talk you out of it.
