The Sierra Club today launched a campaign to defeat the U.S.-China trade pact that the Clinton administration is trying to push through Congress. Sierra Club Executive Director Carl Pope made the announcement by the side of AFL-CIO President John Sweeney, as the labor federation gears up for a rally against the deal on Capitol Hill, which is expected to draw more than 10,000 protestors. Pope said the trade agreement doesn’t include adequate protections for the environment or workers. Congress is expected to vote on the deal in May; the Senate is likely to approve the pact, but its fate in the House is unsure. Some Western Republicans in the House have hinted that they may refuse to support the China trade deal unless Clinton agrees not to designate any more national monuments.
