Glenn Greenwald is an American journalist, author and lawyer. He is perhaps best known for his work with Edward Snowden whereby he published a series of reports exposing details of American and British global surveillance programmes. This work contributed to The Guardian and The Washington Post winning a Pulitzer Prize in 2014.
What Glenn Greenwald does not mention is, David Brock bough out many left wing publications when Hillary Clinton ran for President in 2016. Now these publications and others like them are now allied with the Democratic Party. As far as the CIA goes, in 2013 Obama sign into law that propaganda can be used on the American Public. Maybe Obama really felt threatened by the OWS movement.
