When the Wall Street Journal wrote an editorial bashing Donald Trump’s debate performance, it was perhaps only a matter of time before the GOP candidate took to social media to attack back.

Thursday morning, the Wall Street Journal published an editorial knocking Donald Trump on his trade comments during Tuesday night’s Fox Business debate.

The editorial says,

I’m a free trader, 100%,” said the businessman, after declaring that he opposed the only free-trade deal currently on offer, the U.S. agreement with 11 other Pacific nations. Mr. Trump called it a “terrible deal,” though it wasn’t obvious that he has any idea what’s in it. His one specific criticism was its failure to deal with Chinese currency manipulation. But it took Rand Paul to point out that China isn’t part of the deal and would be happy if the agreement collapsed so the U.S. would have less economic influence in Asia.

Trump then wrote a series of five tweets lashing out at the Wall Street Journal for its editorial judgment and defending his knowledge of the trade deal.
