The Institute for Research and Education on Human Rights (IREHR) produced a in-depth report to track far-right activity in state legislatures. It is a very comprehensive report that you can find here.
Of particular interest is their profile of Susan Delemus, a sovereign citizen. They noted that she joined the new-Hampshire common-law jury (a Facebook group) in 2016 . They advocate creating common-law juries for every county. She’s a member of many other groups as well.
The report also noted that her husband was sentenced to more than seven years in prison for his role in the 2014 Bundy standoff with federal agents. They learned from his plea agreement that he brought firearms and other armed activists from multiple states and performed security for Bundy.
More recently, S. DeLemus has become a covid denier who was pushing ivermectin.
You can read the full profile of her here.
The whole report is worth reading.
