From Reuters: “House passes bill to sue OPEC over oil prices”

The House of Representatives overwhelmingly approved legislation on Tuesday allowing the Justice Department to sue OPEC members for limiting oil supplies and working together to set crude prices, but the White House threatened to veto the measure.

The bill would subject OPEC oil producers, including Saudi Arabia, Iran and Venezuela, to the same antitrust laws that U.S. companies must follow.

And if OPEC says “Go soak your collective head”? What then, O legislators?
