The rumor makes sense:
I suspect that the motive would be to put all the Awans outside of US jurisdiction, thereby removing danger of their personal testimony.
Until they can be killed.
I think that was the intent as well -- if anything, the Clinton e-mail fiasco, Clinton Foundation shady-dealings, and Iran Deal [lit. Treason] all point to heavy-duty, well-entrenched, systemic corruption on the part of our high officials and large parts of the top bureaucracies. At this point, I would be unsurprised if an honest investigation would turn up hundreds of capital crimes.
