Stephen Bannon believed American Muslims plotted to turn the US into an Islamic state.

Evidence

Steve Bannon, who advised Trump in the White House during the first six months of his presidency, repeatedly accused Muslims in America of secretly plotting to infiltrate the US government. Bannon believes the centuries-old crusades between the Christian West and Islam is ongoing. He articulated these views in his 2017 proposal for the film, Destroying the Great Satan: The Rise of Islamic Fascism in America. Although the film was never produced, it demonstrates Bannon’s long-standing belief that American Muslim civil society is plotting to turn America into an Islamic state. — Sahar F.
