Frank Gaffney, a former Reagan administration defence official, has warned of what he describes as a “red-green alliance” between radical Islamist groups and far-left socialists. He argues that these movements have differing long-term aims but share opposition to the US constitutional system; the article presents this as a national-security concern and as part of a wider political debate.

Gaffney made the remarks to Fox News Digital while discussing the Democratic Socialists of America and Islamist movements. The claims were also raised at a Senate Judiciary subcommittee hearing on alleged Muslim Brotherhood networks, where Senator Ted Cruz and Centre for Security Policy analyst Kyle Shideler described a similar alleged partnership; the article does not provide independent evidence establishing the broad claims.
