While Donald Trump has been taking vacations, special counsel Robert Mueller has been working hard on the Russia investigation. Instead of golfing this weekend, we suggest that the former reality show star huddle with his lawyers. Trump s former national security adviser Michael Flynn pleaded guilty to lying to the FBI about conversations with the Russian ambassador and he s fully cooperating with Mueller. As part of the plea deal, Flynn admitted that he was directed by a senior member of the Trump transition team to make contact with Russian officials in December. In addition, Flynn is prepared to testify that Trump as a candidate, ordered him to make contacts with the Russians.This marks the first instance of solid proof that there was collusion between team Trump and a hostile foreign government.On Friday, just after the news broke, the White House insisted that Flynn s guilty plea will not implicate Trump or anyone else in the White House.The White House said in a statement that Flynn was fired for making false statements to Trump officials, and that he worked for the administration for a short time   and that he was a former Obama administration official. The false statements involved mirror the false statements to White House officials which resulted in his resignation in February of this year,  said White House lawyer Ty Cobb.  Nothing about the guilty plea or the charge implicates anyone other than Mr. Flynn. The White House then referred to Flynn as the  former National Security Advisor at the White House for 25 days  as well as  a former Obama administration official. However, the White House left out a few important details. President Obama fired Flynn as head of the Defense Intelligence Agency and he also warned Trump about Flynn during a discussion two days after the election and emphasized that he had concerns about him joining the national security team for the new president.On top of that, just after Flynn was forced to resign, Trump called him a  wonderful man  who was treated unfairly by the media.Photo by David Becker/Getty Images.
