(Washington, DC)  --  The White House says President Barack Obama will be in Portland next Thursday for a fundraiser that will cost at least 500-dollars per ticket.  Officials say plans are also being made for the President to attend a pro-trade event on Friday, possibly at Nike.  The "Oregonian" reports the President is battling with Congress over legislation that's key to the fate of a massive trade pact, known as the Trans-Pacific Partnership, which involves the U.S. and eleven other Pacific Rim nations.  Nike and other global companies are supporters of free-trade agreements that they say increase worldwide sales.
