The Glenn Simpson testimony.

The testimony from Simpson with the two committees painted a picture of Trump that since the 1990's, his businesses seem to be involved in money laundering ,and he was continuously surrounded with Russian organized crime types. He stated that this was not direct proof, but it seems to all be one step away. He says that he gets his information from books, other printed media and records,which means it can be easily checked. If Simpson has made all this up, he could be exposed and his reputation ruined. The same with Christopher Steele. We have heard all of these theories about how the investigation is biased, and they are out to get Trump, but no one has debunked Simpson's information to my knowledge.

Detractors have submitted that there is no evidence of collusion; there may not have been during the election because it wasn't needed.The Russians had him on a string long before that.
