Calling out an edit above, just so others don't miss it.
I'd initially read Khan's comments as saying that there was a 2019 consent order that FB had been noncompliant with.
No, there was a consent decree a decade old (unclear if now or in 2019) that the FTC found hadn't been complied with in 2019.
I suspect that's the 2012 order described here:
@dredmorbius it's both! In 2019 FB settled charges that they had violated the 2012 consent order, paid a $5B fine (without admitting guilt), and signed another consent order. Now the FTC's saying they violated the 2019 consent order as well.
