Pelosi: House Democrats have major concerns about Obama's Pacific trade plan, but door is open

President Barack Obama's bid for a new trade deal didn't get easier Tuesday when the House's top Democrat said her caucus embraces a dozen demands that may be tough to meet.

House Democratic Leader Nancy Pelosi has always walked a careful line between liberals who oppose new trade agreements and others who say the global economy requires such pacts.

Pelosi told reporters Tuesday that House Democrats share the concerns of Rep. Sander Levin of Michigan.

In January, Levin issued an eight-page proposed "resolution of the major outstanding issues" in the administration's bid to conclude a 12-nation Trans-Pacific Partnership. Levin said his support hinges on his numerous proposals being accepted.

Some pro-trade groups noted Pelosi continued to make upbeat comments about trade on Tuesday even as she embraced Levin's list.
