Rob Portman, a long-time champion of international trade, said today he would oppose a free trade agreement “in its current form” which had been negotiated by the Obama administration with 11 other Pacific-rim countries. In a statement, Portman, R-Ohio, said the agreement – called the Trans Pacific Partnership – does not provide a “level playing field” for American workers, adding he would urge President Barack Obama to “to support American workers and address these issues before any vote” on the trade pact.
