Declared War or Genuine National Emergency (via Communications Act of 1934, Section 706 / 47 U.S.C. § 606)
During a proclaimed war or national emergency (as defined by the president), the Communications Act grants the president broad authority over "wire or radio communications."
This includes powers to:
Prioritize government/defense communications.
Suspend or amend FCC rules.
Take over, use, or close communication facilities/stations.
Authorize government control of radio, wire, broadcast, or other electromagnetic-emitting devices.
Historical context: During World War II and other crises, similar powers were used (e.g., FDR considered seizing broadcast networks). The provision remains on the books and is vaguely worded—"war," "threat of war," "public peril," "disaster," or "other national emergency" are not strictly defined.
In practice: This could theoretically allow shutting down or commandeering broadcasters/TV/radio in a true existential crisis (e.g., invasion or massive cyberattack). Modern attempts to use it for political reasons (e.g., revoking licenses of "unfair" outlets) would violate the First Amendment and Communications Act prohibitions on content-based censorship. Courts would almost certainly block it absent a clear, imminent national security threat.
