Deepwater Horizon oil spill - Encyclopedia of Earth
this is a quite good, comprehensive resource that outlines the situations that the thread has been tracking and puts things in context...it's particularly useful for understanding the oil leakage, the environmental concerns, who/which agencies are doing what with how many people and for how long they've been doing it, antecedent spills and so forth.
one reason this disengenuous "who's in charge" stuff can keep surfacing from the drill baby drill set is the lack of information co-ordination. it's the kind of thing that happens inside a short attention span media environment when it processes a long and complicated disaster. a made-for-tv disaster is much faster than this and has fewer moving parts.
