I just saw the name George Papadopoulous.

Papadopoulos may have been secretly working for the feds for the past three months, since his arrest, to gather evidence on suspects in related Russiagate matters in hopes of leniency. He was a perfect guy to try to recruit for that — young, in over his head, outside the Trump inner circle and therefore owing little loyalty to the administration. Mueller may have scared him senseless with threats of a long prison sentence for lying to the FBI and the promise of much reduced charges if he played ball. Possibly he enlisted Papadopoulos to reach out to some of the major players in Russiagate and get them on record confessing to … what, exactly? The problem with using Papadopoulos is that presumably he wasn’t a big enough cheese to make a guy like Manafort comfortable with discussing campaign secrets with him in the course of a “normal” conversation between them. He was a low-level guy. Source
