President Donald Trump's visit to the U.K. was controversial before he even stepped off the plane, but he did not hesitate to further fuel diplomatic flames.

A few hours after they met, Trump took aim at Prime Minister Theresa May by telling The Sun newspaper that "she didn't listen to me." He then proceeded to endorse May's political rival, former Foreign Secretary Boris Johnson, as the U.K's next Prime Minister. 

Trump's comments were aimed at May's "soft Brexit" strategy to maintain similar ties to EU rules for markets, which he sees as a threat to the two-way, exclusive trade deal he hopes to score with the U.K. 

"We would be dealing with the European Union instead of dealing with the UK, so it will probably kill the deal," Trump said. 

He accused May of going against the British people's will by seeking a less disruptive trade agreement with the European Union.

But TheStreet's Martin Baccardax was quick to point out that the Brexit referendum was never a vote on trade deals.

"The British people were not really asked what kind of trade deal they wanted," said Baccardax. "They were only asked whether they wanted to stay or to leave."

For more on that and Trump's busy week in Europe, listen to Baccardax and TheStreet's Scott Gamm break down in this exclusive podcast.
