"We really have a very good relationship".
President Trump and British Prime Minister Theresa May pledged full cooperation on trade and other issues Friday, easing tensions following Trump's explosive interview in which he criticized her handling of "Brexit" and called into question a U.S. -U.K. trade deal.
"If they do a deal like that, we would be dealing with the European Union instead of dealing with the United Kingdom, so it will probably kill the deal", Trump told The Sun in an interview published on Friday.
In addition, Mr Trump claimed he would be negotiating Brexit "much differently" and declared Mrs May "didn't listen to me".
On Friday afternoon, May and Trump were together at a joint press conference after holding previously scheduled talks at the prime minister's country residence Chequers.
As for her relationship with Trump, she said: "We are friends". "I'll be over there just as the decision's coming in", he said.
Mr Trump's remarks about her Brexit strategy had added to the pressure on Mrs May, who has also seen her proposals - agreed by cabinet ministers last week and published in a white paper on Thursday - rejected by Tory Brexiteers. "We wanted to embarrass him and I think we have done that today".

In an interview with The Sun, the President claimed to have warned the Prime Minister on how to handle the Brussels bloc.
Pointing to May, Trump said "this incredible woman right here is doing a fantastic job, a great job", and added that the USA is looking forward to finalising a "great" bilateral trade agreement with the UK.
Tens of thousands of people are marching in central London in the first wave of a whirlwind of protests against the visit of US president Donald Trump, accusing him of torture, misogyny and racism.
Trump's interview with The Sun was full of provocative statements.
There were also demonstrations close to Winfield House, the U.S. ambassador's residence near Regents Park where the president and first lady Melania Trump will spend the night.
The "Trump Baby" blimp that was expected as part of the protests floated up outside of Britain's House of Parliament on Friday morning. And Trump at times drew laughs from some British reporters, who jeered his criticism of the media and openly laughed at his numerous boasts.
"Mr. President, Sir Winston Churchill once said that "to have the United States at our side was, to me, the greatest joy", May told Trump, according to a text of her speech.
Phil Bond, 65, a musician, says that he knows that it is unlikely that the demonstrations will make any difference to the president, but he believes people in the United States will notice.
On Friday night, the president and first lady Melania Trump were welcomed in grand style to Blenheim for a special dinner with May.
