>> Don McGahn's a really good guy. Been with me for a long time.>> He has maneuvered through the White House's mounting legal issues while helping the administration reshape the country's most influential court. But White House Counsel Don McGahn will be stepping down this fall, the news coming from President Trump on Twitter Wednesday.
Reuters' White House correspondent, Jeff Mason.>> On Capitol Hill, Republican lawmakers, in particular, are upset that McGahn is leaving. In part, that's because they've been very pleased with his efforts to stock the judiciary with Republican and conservative-leaning judges. He's been very instrumental in that. And that's one thing that President Trump trumpets as one of his big accomplishments, and that's largely thanks to Don McGahn.
>> But McGahn's relationship with Trump had become strained by pressures from Special Counsel Robert Mueller's probe into alleged Russian interference in the 2016 presidential election. And possibly made worse by recent revelations that McGahn voluntarily sat for 30 hours of interviews with Mueller. Trump reportedly unaware of the extent of the cooperation.
>> McGahn has made it clear that as the White House Counsel, he works for the White House, and his job is to protect the presidency, and not necessarily the individual who is the president. President Trump has certainly shown before a desire to have, whether it be someone at the Justice Department such as Jeff Sessions or others, be there to serve him and to look out for his interests.
>> The departure coming at a tricky time. The recent guilty plea of Trump's personal attorney Michael Cohen, and the conviction of his former campaign manager Paul Manafort, adding to the legal headaches for the President. McGahn has reportedly said a goal of his was to help Trump pick two new Supreme Court justices.
Brett Kavanaugh is his second. Trump saying that McGahn would leave after Kavanaugh's hopeful confirmation. McGahn's departure will be the latest in a large number of high ranking White House officials to leave Trump's side in what has been an unprecedented level of staff turnover.
