Former President Donald Trump's recent social media post calling on his supporters to "PROTEST, TAKE OUR NATION BACK!" in response to his potential indictment by New York officials raises concerns about whether violent extremists will mobilize on his behalf once again. The domestic extremist group Boogaloo Boys has been ramping up recruitment efforts, and law enforcement agencies will need to withstand another violent assault on our system from domestic extremists. While Trump's base may support him in the short term, the former president needs to grow his support beyond his personal following to convince more Americans that Trumpism is about transforming America, not just a cult of personality.
