WASHINGTON (AP) — The chairman of a House energy committee believes dual relief wells have a good chance of plugging the Gulf oil leak.

Rep. Edward Markey, who leads a special committee on energy independence, tells CBS' "Face The Nation" that the government's demand that BP drill two relief wells may be the key to success.

He says those wells, set to be finished in August, double the likelihood of stopping the oil flow.

The Massachusetts Democrat says BP only wanted to drill a single well.
