Michael Hasting ?
He apparently was too given to many Hastings to and fro in an effort to get the goods on Obama and/or Company, and one or more of his Hastings got him killed.
(Sorry for the bad gallows humor, but I am so jaded about the Federal government and its ubiquitous, interminable, destructive, and even lethal, crimes that I despair.)
By the bye, it is Hastings, with an ‘s’.
