Shortly before 4:20 p.m. Tuesday, the White House emailed reporters that President Obama had signed a highly anticipated Executive Order aimed at protecting cyber security.
The order setting up new programs aimed at stopping online espionage and terrorism was already the law of the land, signed by the president. But it was also secret.
The document was "embargoed until delivery of the President's in the State of the Union address" despite the fact it had already been signed.
Such embargoes imposed unilaterally, rather than agreed-upon are not binding on news organizations, which weigh the urgency of the news against the headache of, for instance, being dropped from the White House's distribution list. BuzzFeed abided by the embargo, having participated in a background briefing on the move, but thought it appropriate to report on the unusual delay.
