The biggest revelation in the plea agreement concerns an April 26 meeting in London. Papadopoulos met with the Professor, who told him that the Russians had “dirt” on Democratic candidate Hillary Clinton. The government filing says the Professor said that “the Russians had emails of Clinton,” and in fact “thousands of emails.”
…The FBI first interviewed Papadopoulos in late January, before Mueller was appointed special counsel. Papadopoulos made multiple false statements during that meeting, claiming for example that his conversation with the Professor about the emails preceded his work for the Trump campaign. He also downplayed his contacts with the female Russian national and claimed they’d taken place before he joined the Trump campaign. After meeting with the FBI again in February, Papadopoulos deleted his Facebook account and got a new cellphone number. Then, on July 27, 2017, Papadopoulos was arrested upon arriving at Dulles International Airport near Washington, D.C.
…Papadopoulos’s plea is notable because it represents a guilty plea by a Trump campaign official related to ties with Russia. The fact that he was arrested in July, but that Mueller managed to keep his case against him secret until Monday morning, is a reminder of how tight-lipped the special counsel’s team has proven, and that Mueller may know things that have not yet been publicly reported or disclosed. The plea deal indicates that Papadopoulos is now cooperating with the probe.
