Top Trump administration officials have spent the days since Kirk’s murder using it as an excuse to crack down on the political opposition. To experts and former government officials who have devoted their lives to studying and fighting violent extremism, this narrative is galling. The office that Braniff ran, known as CP3, focused on fighting violent extremism. Trump signed an Executive Order on Tuesday labeling Antifa as a domestic terrorist organization, the first time such a designation has been applied to a domestic group (no matter how ill-defined). When Trump reentered the White House, Braniff told TPM, 43 states were working with CP3 on strategies to counter violent extremism.
