The Smith-Mundt Modernization Act of 2012?
Yes. Before that, since 1948, the government was not allowed to engage in essentially domestic facing propaganda. Of course now it seems obvious they didn't follow those rules. However in 2012 obama and co pushed that to be amended.
Kind of hard to believe noone really heard about this till now. Youd think a president unleashing propaganda on his own country would he a huge story, but i guess that requires someone to actually report on it.
