Fireworks erupted over international trade during the first 2016 presidential debate on Monday as Donald Trump repeatedly interrupted Hillary Clinton to slam her support for international deals.

{mosads}After a subdued start to the Monday night debate, Trump became animated when the topic turned to trade, blasting former President Bill Clinton for approving the North American Free Trade Agreement (NAFTA).

“Your husband signed NAFTA, one of the worst things that ever happened in the manufacturing industry,” Trump said. “You go to New England or Ohio or anywhere, you see devastation because of NAFTA.”

The Republican presidential nominee’s aggressiveness had Clinton on the defensive, and he pressed the issue, accusing her of supporting President Obama’s Trans-Pacific Partnership, a controversial trade deal that the former secretary of State now opposes after having initially praised it.

“You were totally in favor of it, then you heard how much I was against it and you said you couldn’t win,” Trump said.

“That’s just not accurate,” Clinton responded. “I was against it once it was finally negotiated and the terms were laid out.”

Trump shot back: “You called it the gold standard of trade deals. You said it’s the finest deal you’ve ever seen, and then you heard what I said about it and all of a sudden you were against it.”

“Well, Donald, you live in your own reality, but it is not the facts,” the Democratic nominee replied.

Trump sought to keep the pressure up.

“There are different views about what’s good for our economy and leadership in this world—” Clinton said, before Trump interjected.

“But you have no plan, secretary, you have no plan!” Trump said.
