They also had write access, and one of the team members was fired from his old job for stealing company data.

There is something about pre clearance and process checks on this which troubles you? It's entirely routine across government and private sector to ask people who are being given high privilege access to data to be reviewed and to discuss approaches to data handling.

I am extremely troubled by how low-doc this process has been. Finding out what happened, what integrity checks on data, who had visibility will be next to impossible.

And we've already had indications some of the people doing this work would fail even the most basic of clearance checks. No conspiracy theory needed to ask why these people, in this manner, this rapidly, this un-documented got rapid access to critical, strategic data.

I agree! The people elected Trump to do this exact audit!
