It is terrific reading - and I think it's part of the strategy:
- indict people they believe actually committed crimes, regardless of whether or not they get to actually prosecute due to their physical location
- get arrest warrants issued - if they're in the US, take them into custody, if they're not, keep an eye on them until they travel to a country where they can be legally detained and transferred to the US
- then, get them to make a deal.
I am guessing that this is the Grand Jury that Mueller is using for his investigation. Though it seems a possibly futile gesture, this is all part of exploring all the facets of the interference in the 2016 investigations, and I think it will bear some fruit.
Also, Melania really doesn't do it for me.
UPDATE: Mueller's office put out a statement about these charges, so it is the Grand Jury he is using.
