President Donald Trump‘s bold action to root out foreign sources of domestic unrest marks a return to the types of investigations the Department of Justice has long ignored. 

In his recent memorandum, “Countering Domestic Terrorism and Organized Political Violence,” Trump pinpointed multinational organizations, nonprofit groups, and American citizens with close ties to foreign governments, agents, citizens, foundations, or influence networks as likely focuses for review. And, as he identified, the Foreign Agents Registration Act is just the tool to do it.
