So, about the crazed slaughterer Nikolas Cruz...

Nicholas Jacob Cruz was unofficially taken in by the parents of one of his friends.
There was no official adoption, and Nicholas Jacob Cruz is a natural born citizen
and a white nationalist affiliated with the "Republic of Florida", a terrorist organization.

Unless there has been an update, the story the ADL put out about his connection to this white nationalist group was based on a lie. Cruz had connection at all. 

There was an update around 12 noon on MSNBC that mentioned that Nicholas Jacob Cruz had carved a
swastika symbol on his bag, and that his browsing habits involved some white nationalist web sites.

Also there is the matter of some communications with the "Republic of Florida".
It is just that law enforcement was attempting to initially conceal from the public
that the nature of the crime was Alt-Right involved.

Although there is a lot of interference from Russian Trolls and 4chan users
trying to cast doubt and confusion on the incident in an attempt to
prevent anything from being done about non muslim related terrorist attacks.

We should not dismiss the possibility of Russian coordinated attacks and
mass shootings on American soil. Mass shootings and terrorist attacks
organized and funded by Russian operatives, including the funding
and training of U.S. citizens to commit acts of terrorism in the U.S.
