I sort of doubt it. From story about an antivaccination meeting.

Bigtree produced the 2016 documentary “Vaxxed,” which contends the Centers for Disease Control and Prevention has tried to cover up links between autism and the MMR vaccine — a view that has been widely disputed.Sussman is a well-known civil rights lawyer representing the parents of unvaccinated children with religious exemptions in a lawsuit against Rockland County’s measles emergency.

The following day, Handler and Bigtree were part of an anti-vaccination rally in Albany that brought hundreds to a gathering outside the Capitol.

[my emphasis].  “The following day” after what?
