The New York Times is reporting that White House Counsel Don McGahn 'has cooperated extensively' with Special Counsel Robert Mueller's Russia probe. He has cooperated to such an extent that McGahn has revealed information to Mueller that the Special Counsel did not know of previously.
> The White House counsel, Donald F. McGahn II, has cooperated extensively in the special counsel investigation, sharing detailed accounts about the episodes at the heart of the inquiry into whether President Trump obstructed justice, including some that investigators would not have learned of otherwise, according to a dozen current and former White House officials and others briefed on the matter.
> In at least three voluntary interviews with investigators that totaled 30 hours over the past nine months, Mr. McGahn described the president’s furor toward the Russia investigation and the ways in which he urged Mr. McGahn to respond to it.
> Mr. McGahn and his lawyer, William A. Burck, could not understand why Mr. Trump was so willing to allow Mr. McGahn to speak freely to the special counsel and feared Mr. Trump was setting up Mr. McGahn to take the blame for any possible illegal acts of obstruction, according to people close to him. So he and Mr. Burck devised their own strategy to do as much as possible to cooperate with Mr. Mueller to demonstrate that Mr. McGahn did nothing wrong.
