US SENATE CUTS OFF STALL TACTICS ON GULF BILL Confronted by new hostilities involving U.S. forces in the Gulf, the U.S. Senate voted to end Republican stalling tactics and limit debate on a measure that could give Congress a larger role in Gulf policy. The measure, however, does not require President Reagan to comply with the 1973 War Powers Act as does a related Senate bill. The controversial War Powers Act could require a pullout of U.S. forces from the Gulf. The Senate voted 67-28 to stop a filibuster and limit debate to 30 hours on a bipartisan measure that requires Reagan to report to Congress on Gulf policy within 60 days and calls for a resolution to be passed in the House and Senate on the situation in the volatile waterway 30 days later. The resolution could be about any Gulf-related issue, including an expression of support or of disapproval for Reagan's policy of protecting 11 Kuwaiti tankers from Iran in the waterway. The Pentagon said the 12th U.S.-protected convoy began moving through the Gulf early Tuesday.
