The House Select Committee is set to investigate the January 6 Riot on July 21, 2022, during its latest public hearing. At the heart of the issue is Trump’s possible engagement with rioters and fringe nationalist militia groups such as the Proud Boys, Three Percenters and Oath Keepers. Amy Cooter, a senior lecturer in sociology at Vanderbilt University and militia expert, explains what drives these groups and their complicated relationship with Trump and the government.
