Why didn’t they announce at a scheduled time on a friendly network? Like there has to be an interesting story here, it would make a good or tv show.

It sounds you actively want to read too much into it and find some conspiracy.

Announcing a scheduled time would be as silly as your question. As soon as they scheduled it, it would leak and they would lose control of the narrative.

I don’t know if you noticed this, but the internet is kind of a big deal and politicians have been using social media as part of their campaign and communications for a while.
