NEW ORLEANS (AP) — Louisiana’s Republican U.S. senator blasted oil giant BP PLC on Tuesday for what he called its attempt to run from its full cleanup responsibilities for the nation’s worst offshore spill, the 2010 disaster that left the Gulf Coast heavily oiled.

U.S. Sen. David Vitter also charged during a field briefing in New Orleans that the Coast Guard had “too cozy” a relationship with the energy company. He spoke during a briefing of the Committee on Environment and Public Works, a Senate body that oversees environmental issues.
