A Twitter spokesperson has confirmed with TechCrunch this morning that Trump has deleted three tweets that led to the temporarily suspension of this account last night.
The President's account is to remain locked 12 hours after his deletion of the tweets (seen below). While we don't have exact timing on when the countdown started, he has yet to tweet from the account. The account also still bears the warning that, "this Tweet is no longer available because it violated the Twitter Rules."
So whenever he deleted the three tweets, 12 hours after that he'll be let back into his account. Could be in the next few minutes, could be hours from now.
And he's banned from Facebook, IG, Twitch, etc., so whatever he has to say he's gonna say it on Twitter (before they inevitably ban him for good).
