Fact - Only 4 cases are associated with protests. None yet causally linked by state/fed authorities. I don't think they're lying. Both LITERALLY TOLD PEOPLE TO NOT ATTEND PROTESTS & have no reason to cover up.
Another argument supporting this lie - 'Maybe the protests DID cause spread that's not captured through testing' OK let's play:
People forget the anarchic fury of #BlackLivesMatter riots in USA that catalyzed global protests in the first place.
