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.
The measure passed in a 324-84 vote, a big enough margin to override a presidential veto.
The legislation also creates a Justice Department task force to aggressively investigate gasoline price gouging and energy market manipulation.
The Senate previously approved similar legislation as part of a broad energy bill. However, the OPEC-suing provision was removed after White House opposition in order to get the underlying energy legislation signed into law.
