WASHINGTON -- The House of Representatives will quickly get down to unfinished business once it returns from the holiday recess: defending trading partners that engage in slavery. The House, according to sources familiar with trade deal negotiations, plans to strip Senate language from fast-track legislation that would ban countries that are the worst human-trafficking and forced-labor offenders from being part of big trade deals like the Trans-Pacific Partnership. The provision will be removed by House Ways and Means Chairman Paul Ryan (R-Wis.) through a customs bill that will come to the floor after the fast-track bill, sources familiar with the planning told The Huffington Post. On the eve of the holiday recess last week, the Senate passed legislation giving President Barack Obama fast-track authority to shepherd trade deals through Congress.
