ARLINGTON, Va. — Conservative provocateurs Jacob Wohl and Jack Burkman held a chaotic press conference in a suburban driveway to float rumors about Joe Biden’s health even as sexual assault allegations against South Bend, Ind., Mayor Pete Buttigieg fell apart.

Wohl and Burkman are accused of pressuring male college student Hunter Kelly into making sexual assault claims against Buttigieg, who is gay. The pair at times competed with the sounds of airplanes and a high-volume garbage truck that arrived to collect Burkman’s trash.
