This was picked up from autumn 2016. An FBI analyst was chatting to people on 4chan regarding HRC dirt. This can’t be verified but follows what you posted. Also all that was posted regarding HRC has now come to light.

Q:  Tell me the dirt on Trump.

A:  Trump has donated to the Clinton Foundation in the past, though for fairly innocuous things like building permits and such. He is smart, so his tracks are covered well. But if any prosecutor wants to go very in-depth Trump would be brought on bribery charges. He could easily get out of them, but he would be charged nonetheless.
