Its an open question as to whether a sitting president can pardon himself. We've never had to do it before because we've never had a president that both required it and also had the gall to use it. Nixon reportedly considered it.
One can keep crying "fake news" all they want with the rest of the birthers. But its now an undisputed fact that:
1) Trump's son met with Russian operatives to coordinate dirt about his oppponent. And then he lied about it.
2) Donald Trump has been forced to acknowledge he dictated that lie after initially denying it
3) Trump fired the FBI Invesitgator in charge of Trump's investigation. And made it very clear the reason he was fired was because of that investigation
4) Trump has publicly expressed regret over hiring Jeff Sessions as his attourney general because Sessions refueses to obstruct justice on Trump's behalf.
5) Despite all of the interference there are several convictions and indictments of Trump's handpicked inner circle...including the chief ececutive of his campaign, national security advisor, and foreign policy advisors....and counting.
I have no confidence the current Congress would impeach the president given these facts. But some Republican Senators said ending the investigation or attempting a presidential pardon would be grounds to do so.
