Trump’s rhetoric is unusual for a presumptive Republican nominee for president, placing him in direct conflict with Washington business groups who have traditionally been allies of the GOP.

The U.S. Chamber of Commerce, which doesn’t endorse presidential candidates, unloaded on Trump during the jobs speech, rebutting him point by point on his criticism of trade deals like the Trans-Pacific Partnership (TPP).

In an op-ed in the Washington Post, the Chamber’s President and CEO Thomas Donohue said both Clinton and Trump are wrong on trade.

“Let’s get one thing straight — ripping up our trade agreements, as presumptive Republican presidential nominee Donald Trump suggests, and raising a tariff wall around the U.S. economy wouldn’t bring those jobs home,” Donohue wrote in the Washington Post.

“Instead, it would decimate millions of high-wage American jobs and slam families trying to make ends meet.”
