JEFFERSON CITY, Mo. (AP) - Republican Congressman Roy Blunt of Missouri is sponsoring legislation that could cause oil companies to pay for a greater portion of a cleanup following a spill.
But Democratic Secretary of State Robin Carnahan says Blunt's proposal doesn't go far enough. She wants to hold oil producer BP responsible for the entire cost of the spill in the Gulf of Mexico.
Blunt and Carnahan both are running for Missouri's open U.S. Senate seat.
Federal law caps liability for oil spills at $75 million.
Blunt filed legislation Thursday to make the liability cap equal to the last four quarters of the company's profits or double the current limit, whichever is greater. A Blunt spokeswoman estimated the legislation could make BP liable for about $20 billion.
