A former US Army psychological warfare officer says that Tucker Carlson was fired by Fox News because of the regime's agenda to maintain an "uninformed semi lobotomized quasi retarded population."

The remarks were made by US counter-terror expert Scott Bennett.

Carlson and Fox News "parted ways" on Monday with speculation still raging as to the specific reason why the network canned its highest rated and most popular host.

According to Bennett, Carlson posed too much of a threat to institutional power because he turned Americans into proper "researchers and thinkers".

Carlson offered an "intellectualism, truthfulness, and an analytical depth that no other news personality has ever done in the history of the United States as far back as I can remember," said Bennett.
