PORTLAND, Ore. — President Obama appears to be a Nike fan. Golf outings often find him decked out from head to toe in apparel featuring the emblematic company swoosh. Now the president is putting the company logo on his trade agenda.

But in choosing the giant athletic wear company as a backdrop to make his pitch for a free trade deal, Obama has stirred a hornet’s nest.

• THE TRANS-PACIFIC PARTNERSHIP

Nike, a major exporter, employs more than 8,500 workers in Oregon, many in well-paying design, research or marketing jobs. But most of Nike’s factory contract workers are in Asia, with the largest number in low-wage Vietnam.

“It is a perverse place to try to go and sell a trade agreement that the American public thinks would make it easier to offshore our jobs and push down our wages,” said Lori Wallach, the director of Public Citizen’s Global Trade Watch.

For Obama, the trade dependent Pacific Northwest is a natural place to make his case for trade negotiating authority and to promote a 12-nation Trans-Pacific trade agreement. Congress is debating whether to give Obama so-called fast-track authority to complete that and other trade deals. Obama’s toughest sell is with his own Democratic allies, who fear the loss of American jobs and weakened financial and environmental rules.

Nike, with its massive outsourcing of manufacturing, provided Obama with an opportunity to talk about labor standards he seeks to enforce with trade partners, particularly Vietnam where the U.S. concedes worker rights protections fall short of international standards. Of the 11 countries the U.S. is negotiating with in the Trans-Pacific talks, Nike has contract factories in seven of them.

White House spokesman Josh Earnest says the stop at Nike will “illustrate how a responsible trade agreement that includes enforceable labor and environmental standards would strongly benefit middle-class families and the American economy.”

But Obama’s visit has created a backlash. Nike represents what many liberal groups and labor unions criticize about trade deals: the potential for shifting U.S. jobs to other countries with cheap labor and few worker protections. On Thursday, Sen. Bernie Sanders of Vermont, who recently announced he is challenging Hillary Rodham Clinton for the Democratic presidential nomination from the left, called on Obama to cancel the trip.

Two decades ago, Nike came under heavy criticism for its use of foreign sweatshops, including numerous reports of child labor, low wages and poor working conditions. Under intense public pressure, Nike improved conditions and eventually wages climbed, minimum age requirements were put in place and Nike increased training and monitoring at the factories.

“We’ve made significant improvements and driven positive change for workers in contract factories that make Nike product,” Nike spokesman Greg Rossiter said in a statement to The Associated Press.

Despite the advances and Nike’s image makeover, labor issues have continued to plague its contracted manufacturers. An Associated Press investigation in 2011 found that workers making Nike-owned Converse sneakers in Indonesia said supervisors abused them physically and verbally. And in its latest report on “sustainable business performance” Nike found that one-third of its contract manufacturers in 2013 did not meet its minimum standards – an improvement over 2011 when half of the manufacturers fell short. Most of the problems were over hours and wages.

“Nike fully supports the inclusion of strong labor provisions because we believe they will drive higher industry standards and create economic growth that benefits everyone,” Nike’s Rossiter said.

At a breakfast with reporters Thursday, Rep. Sander Levin, D-Mich., said he met a Vietnamese woman who spent more than four years in jail for trying to organize an independent labor union. Levin is the top Democrat on the Ways and Means Committee, which handles trade bills. He said the fast-track legislation and Trans-Pacific trade talks don’t do enough to force Vietnam to raise its labor standards.
