At the press conference Trump was asked by reporters if he thought the British-U.S. relationship was a special one, and the president labeled the bilateral relationship as "the highest level of special".
While Trump did meet with the Queen on Saturday, his visit has done little to fix his negative image in the U.K. At the same time as he was dining with British Prime Minister Theresa May on Friday night, an interview the president had conducted with The Sun was released in which he criticized May's "soft Brexit" deal and said it could "kill" any prospect of a trade deal with the United States. The newspaper released lengthy clips of the interview that showed Trump saying that May did not take his advice on how to handle Brexit, saying she "wrecked it".
Trump called the Sun story "generally fine" but said that some of his remarks were left out.
Trump said the pair discussed Brexit and "she said it's a very - and she's right - it's a very complex problem, I think nobody had any idea how complex it was going to be", he revealed, without going further.
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.
"The relationship is further back than it was a few days ago", Dr. Jacob Parakilas, deputy head of the US and Americas program at London-based think-tank Chatham House, told Xinhua in an exclusive interview on Friday.
Mr Trump is due to meet Vladimir Putin, who has rejected the nerve agent claims, at a summit when he finishes his four-day visit to Britain.
