Directly, USAGM controls VoA, RFE/RL, RFA, etc. Wikipedia allows these as "reliable sources". Twitter doesn't tag them.
The current CEO of NPR is a former USAGM exec. PBS FRONTLINE has unprecedented access to interviewing top DoD/State officials for stories that advance their agendas. Interesting.
Indirectly, all the establishment media has close ties to national security. NYT admitted that potentially sensitive stories need to get screened by the government before publishing. That's state control over media where it counts.
