Responding to a question about the Islamic State group, Elibiary wrote, "As I've said b4 inevitable that 'Caliphate' returns."

The tweet was part of a string of posts deemed inappropriate for a senior government advisor, including one where he said he considered the United States to be an "Islamic country" and another where he suggested that those in the national security "uber hawks camp misread 9/11."

After the June tweet, Elibiary was asked if he supported the "inevitable Caliphate," and he responded by saying that the U.S. is moving towards engaging with radical Islamic groups, including the Muslim Brotherhood, The Washington Free Beacon reported.
