The Trans-Pacific Partnership is the biggest thing to hit international trade since the North American Free Trade Agreement.
Negotiations are ongoing between 12 Pacific Rim countries, including the United States, Canada, Vietnam and Chile. Advocates say the agreement is necessary to ensure smooth trade between nations. Opponents call it a corporate power grab.
"Since NAFTA we've lost one in four U.S. manufacturing jobs," she said.
She added that we've lost more than 300,000 jobs in North Carolina during that time.
"I do recognize that a lot of manufacturing jobs have been lost in the United States," She later added, "This is a better deal for us, because we need more transparency and disclosure."
She argues this agreement is more comprehensive than those in the past.
"Most free trade deals are about reducing tariffs," Krupp said. "But this trade agreement is going a lot further because tariffs are already pretty low."
Instead, this agreement focuses on getting rid of red tape and bureaucracy to make trade between countries easier, Krupp said.. This includes equalizing intellectual property rights and allowing foreign countries to be more competitive in countries that prefer local firms.
Krupp says that these regional agreements make sense in a complicated world.
"When you have the entire membership of the WTO... trying to reach agreement on all of these issues, you just don't get anywhere," Krupp said.
But the secrecy under which these negotiations has taken place concerns many critics.
"I think the reason this is being kept secret is because they know the American people are going to be outraged," McMillan said.
