President Obama will visit Nike’s campus near Beaverton, Oregon on Friday to make his case for the United States to sign on to the Trans-Pacific Partnership trade agreement.

It’s a proposed trade agreement between the U.S. and Australia, Brunei Darussalam, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, and Vietnam. If the deal is approved, it would cover almost 40% of the world’s GDP.

Sen. Ron Wyden, D-Oregon, has been a major advocate of the TPP in Congress. Opponents of the deal have criticized it however for several reasons, including potentially sending domestic jobs overseas.
