Reporter: The administration still has security concerns about TikTok, even though the campaign has now joined it?
Kirby: I cannot speak, nor will I speak for the campaign…nothing has changed about the national security concerns from the NSC's perspective about the use of TikTok on government devices. That policy is still in place.
Reporter: Surely there must have been some conversation between the White House and the campaign of whether it was appropriate for the campaign to use it?
Kirby: I can't speak to that.
