On a new campaign website, Paul Ryan’s primary challenger, Wisconsin businessman Paul Nehlen, warns that the Trans-Pacific Partnership “will be the fundamental undoing of America.”

On Wednesday, volunteers for Nehlen’s campaign announced the launch of a new website, PaulRyanFiles.com, “dedicated to tracking and exposing the numerous ways in which 18-year incumbent Paul Ryan has betrayed the people of his congressional district, his state, and his country.”

On the website, Nehlen writes that Paul Ryan “has betrayed Wisconsin’s 1st district” and “has betrayed this country and its citizens.”

In particular, Nehlen highlights Ryan’s push to fast-track the Trans-Pacific Partnership (TPP): “I would run for congress against Speaker Ryan on this issue alone. This trade deal isn’t just bad. It will be the fundamental undoing of America.”

Nehlen writes that the TPP would be “worse than NAFTA. It sets up a super-national organization similar to the European Union. We know all too well what the European Union is doing right now, and we don’t want that to happen here.”

Indeed, as Senator Jeff Sessions has pointed out, the agreement creates a Trans-Pacific Partnership Commission, which Sessions has described as a “Pacific Union”—a “self-governing and self-perpetuating Commission with extraordinary implications for American workers and American sovereignty.”

This “massive, job-killing international ‘trade’ deal,” Nehlen writes, “sells out American workers. It sells out American business and industry. It will kill the economy in this district, never mind the rest of the country.”

Wisconsin exit polling data shows that a majority of Wisconsin GOP voters agree that foreign trade deals take away U.S. jobs.

Nehlen writes:

Paul Ryan is the poster boy for outside interests. He’s a career politician who’s reaped his ever-growing mountain of campaign cash primarily via large donations coming straight from inside the Washington Beltway. In helping out his big donor cronies, Paul Ryan votes against the manufacturers, small businesses, workers, taxpayers, and families of Wisconsin’s 1st Congressional District on issue after issue.

“Paul Ryan isn’t representing our district. He’s representing the big businesses and big banks that pour money into his campaign coffers. It’s their agendas he’s carrying forward with his votes in Congress…not ours,” Nehlen writes.

Nehlen notes that in addition to Ryan’s trade agenda, Ryan has “supported numerous policies and measures that are already doing profound damage to this nation’s economy, to our security as citizens, and to our personal freedoms… He’s embraced out-of-control spending via Omnibus spending bills. He’s used budgets to fund dangerous immigration policies that put American lives at risk. He’s voted for bills that compromise our constitutional and civil liberties.”
