It seems reasonable to assume from this that at the meeting with RC Jr. Russia was offering damaging information about Clinton in exchange for repeal of the Magnitsky Act or at least a dilution of it.

RC Jr's claim that nothing was actually shown to him would be accurate but the Russian lawyer as a matter of course would not have shown what they had until they knew what they would get in return.

I doubt US investigators will miss this point. RC Jr. is looking guiltier every day.
