WASHINGTON (AP) - Two Democratic senators, Barbara Boxer of California and Bill Nelson of Florida, say they've asked President Barack Obama to give the Navy a bigger role in the effort to clean up the Gulf oil spill. The job is now now being overseen by the Coast Guard.
But Defense Secretary Robert Gates says the Pentagon has already "offered whatever capabilities we have." He says, "We don't have the kinds of equipment or particular expertise."
The senators spoke on CBS' "Face the Nation" and Gates on "Fox News Sunday."
