Inadequate human intelligence, poor communication and unheeded warnings contributed to the deadly debacle a year ago.

Michael Miselis "is no longer an employee at Northrop Grumman," a company spokesman told FRONTLINE and ProPublica in an email.

Trips to Ukraine. Mixed martial arts events with a white supremacy flavor. California’s Rise Above Movement goes on the road.

Michael Miselis took part in the violent Unite the Right rally in Charlottesville. So far, it hasn’t damaged his standing at Northrop Grumman.

Vasillios Pistolis had bragged online about his affiliations and his role in the violence in Charlottesville last year. He is now likely to be forced from the Marine Corps.

A former Marine says he alerted the Corps to a white supremacist in its ranks last October. Six months later, he wonders how seriously the Corps is investigating.

The probe follows a ProPublica and FRONTLINE report on white supremacists in the military.

A Marine took part in the violent assaults in Charlottesville last summer and later bragged about it online with other members of Atomwaffen, an extremist group preparing for a race war. The involvement of current or former service members -- often with sophisticated weapons training -- in white supremacist groups has long been a concern.
