A family-run network of pro-gun groups is behind five of the largest Facebook groups dedicated to protesting the shelter-in-place restrictions, according to an NBC News analysis of Facebook groups and website registration information.

The groups were set up by four brothers — Chris, Ben, Aaron and Matthew Dorr — and have amassed more than 200,000 members collectively, including in states where they don't reside, according to an NBC News analysis based on public records searches and Facebook group registrations.
