As more details emerge about those who attacked the U.S. Capitol on January 6, it’s becoming clearer that the insurrection was not the work of a “fringe” group, but rather the result of a decades-long conservative effort to undermine democracy, according to author Brendan O’Connor. “The events of January 6 were not just months, but years, decades, in the making,” says O’Connor, who notes that major Republican donors and prominent conservative groups were connected to the Trump rally that immediately preceded the Capitol riot.
