Ms May and Mr Trump both spoke of the importance of the "special relationship" between their two countries, something that Brexit supporters hope will reap benefits when Britain leaves the European Union, allowing it to forge closer trade ties with the world's biggest economy. That announcement sparked several high-level resignations-including Foreign Secretary Boris Johnson and Brexit Secretary David Davis. Some signs read "Dump Trump", "Lock Him Up" and "There Will Be Hell Toupee".
Brexit "creates an opportunity to reach a free trade agreement that creates jobs and growth here in the UK and right across the United States", she said.
Following a visit to the Royal Military Academy at Sandhurst on Friday morning, Trump flew to Chequers in Buckinghamshire by helicopter to avoid the protesters who are demonstrating his visit.
He said "the deal she is striking is a much different deal than the one the people voted on".
He also told the tabloid that he had shared advice with May during Britain's negotiations with the European Union, but said May ignored his advice.
Dawn Butler, an lawmaker from the opposition Labour Party with responsibility for women and equalities, told TIME: "Theresa May has failed to be a critical friend to Trump".
The four-day trip, which will include talks with Prime Minister Theresa May, tea with Queen Elizabeth II and a private weekend in Scotland, is set to be greeted by a mass protest in London on Friday - even featuring a giant "Trump baby" balloon.
Trump also said former foreign minister Boris Johnson, who resigned this week in protest over the plan, would make "a great prime minister".
Interestingly, older people are more likely to think Mr Trump was wrong to express his opinions on Brexit, but young people are more likely to think that Britain would be unwise to trust him in trade negotiations. I like a lot of people in the United Kingdom. "He obviously likes me and says very good things about me", he added.
"The sense of betrayal in this country will be huge, and I very much hope that she's out of office before too long", Farage said.
Fox News, the supportive network Mr Trump is known to watch extensively, called him the "Disruptor in chief", saying he had delivered a "bombshell interview" that had "thrown fuel onto the country's already fiery political debate".
President Donald Trump nearly never apologizes, which makes his comment that he had tried to apologize to Theresa May, albeit without admitting he did anything wrong and wrapped in a shot at the press, so interesting.
With its straw-blond hair, questionable face tan and unmistakably out-of-proportion hands, a blimp meant to depict President Donald Trump as a screaming baby flew outside the Parliament building in London Friday. "But when they make you feel unwelcome, why would I stay there?" "I think you are losing your culture".
In a near replay of their famous hand-holding at the White House, the president briefly took Mrs May's hand after arriving as they went up the stairs into the palace following a performance from a military band.
Trump spoke out against the balloon and against London mayor Sadiq Khan, who approved its launch.
"Take a look at the terrorism that is taking place".
His criticism of Britain's anti-terror policies after a series of attacks in 2017 also did not go down well.
"I think he has not been hospitable to a government that is very important".
The President said the newspaper didn't include the "tremendous things" he said about Ms May in the interview. "As he said in his interview with the Sun she "is a very good person" and he "never said anything bad about her", she said. "I think it's fine".
