WASHINGTON (Reuters) - Republicans in the House of Representatives will approve a new free trade agreement with Central America late on Wednesday with the help of a few Democrats, House Majority Leader Tom DeLay said. "It will be a tough vote but we'll pass CAFTA tonight," DeLay told reporters after a meeting between President Bush and House Republicans. "We will honor our commitments to the south, we will protect our national security and will do it all with very few Democrats."
