What's going on is the continued arrival of oil washing ashore, although in lesser amounts than during the summer. Dire predictions of environmental Armageddon have yet to materialize, but there's also no consensus on how badly the ecosystem has suffered.
At first, no one could agree on how much oil was spilling into the Gulf; now there's disagreement over how much remains. A commission this week faulted Barack Obama's administration for multiple missteps, including an effort to block scientists from telling the public how bad the spill could be early on.
That decision to attempt "...to block scientists from telling the public how bad the spill could be" demonstrates, very clearly, how how desperately Obama wanted to protect BP, one of his biggest campaign contributors, no matter the cost to American human health and safety.
