Open letter to US President Donald Trump (2018)
Context: Dear Mr. President:
Former CIA director John Brennan, whose security clearance you revoked on Wednesday, is one of the finest public servants I have ever known. Few Americans have done more to protect this country than John. He is a man of unparalleled integrity, whose honesty and character have never been in question, except by those who don’t know him.
Therefore, I would consider it an honor if you would revoke my security clearance as well, so I can add my name to the list of men and women who have spoken up against your presidency.
