You do realize they are going to indict (probably already have but under seal) essentially every major politician including theit bullshit governor and banker in Puerto Rico for corruption, right?
Money laundering, bribery and drugs.
It's a precursor to the real US citizen onslaught of the same theme. A lot of governors, attorneys general, congressmen, senators AND bankers.
The PR effort is essentially an A/B test to help the administration (military intel) know how to calibrate and message the larger effort. All without impacting any real Americans at first.
