“For more than two years, I expressed concern that any final TPP agreement needed to address currency manipulation, provide a level playing field for American automobile manufacturers, and protect U.S. biologics," Portman said. Unfortunately, the Obama administration moved forward without addressing these concerns, and that is why I opposed the TPP.” Portman, in 2015, voted in favor of fast-track legislation for the Trans-Pacific Partnership, which allowed Obama to send the final trade deal to Congress for a vote, with no opportunity for amendments.
