Whose defense secretary is Jim Mattis? Obama's? Trump's? a temporary holder of the post? What?
Why is so much reported with such incompetent ambiguities?

The military might as well have the killers vet themselves! The military seem to have no more competence that Obama's flying monkeys "vetting" terrorists.
What gives?
