If he didn’t have a warrant or court authorization I’d think this is a gigantic issue.

If he did have a warrant it would still be a huge issue to know how he got it, why it should be issued for the transition period, etc.

Very good question.

I hadn’t actually considered the “Tansition Period” part of that, even though it was blatantly obvious as something to question.

I had merely wondered on what basis he could request anything after all the interviews. It’s fairly obvious there was nothing found with which to justify a subpoena for these sorts of documents.

My understanding is that the Trump legal team expected a request from Mueller for these documents, and were prepared to turn them over when asked. However, during the questioning of WH personnel which took place this week, the Trump legal team discovered that Mueller was already in possession of documents, even ones that the Trump people considered privileged, and that the documents had been obtained by Mueller illegally from the GSA, on whose servers the transition teams emails had been hosted.

This is a big deal.

It also reeks of the tactics of Andrew Weissmann, one of crooked Mueller's chief investigators, who has a long history of prosecutorial misconduct.
