"I reject politically motivated violence in all forms. Those who take the law into their own hands for political reasons — whether they are Antifa, Black Lives Matter protestors, the Proud Boys, or others — must be held accountable," Graham said, calling for the January 6 rioters to be "held accountable."
"I was in the Capitol on January 6 and know it was one of the darkest days in American history," he added.
"For us to remain a nation of laws, not men, we must speak with one voice when it comes to politically motivated violence," Graham wrote. "All Americans are entitled to have a speedy trial and their day in court, but those who actively engage in violence for whatever political cause must be held accountable and not be forgiven."
