Rachel Maddow:

President Obama today promised a full investigation into the Deepwater Horizon oil disaster. Obama said the administration will consider whether what has happened amounts to a crime and won't allow new offshore drilling until we know what went wrong.

As Obama spoke, he was flanked by the two co-chairs of the bipartisan National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling. The Republican co-chair, William K. Reilly, has spent a career in the industry he'll now probe. A former chief of the Environmental Protection Agency, Reilly currently serves on the board of directors of:

* ConocoPhillips
* DuPont, which provides technologies for oil and gas extraction
* Energy Future Holdings, a Texas-based electric utility company
