Wednesday’s mob insurrection at the Capitol building in Washington, D.C., is unlikely to be the last violent action from far-right extremists, who may also be using the week’s extraordinary events to recruit members for a swelling coalition around outgoing president Donald Trump, according to experts on extremism.
