The Foreign Secretary plunged the government’s response to the President’s cancellation into chaos as he accused Labour’s top brass of jeopardising the special relationship.
His comments came as Downing Street insisted the “strong and deep” partnership between the UK and US will continue.
Mr Trump said he had decided to abandon the proposed visit because of his disgust at the deal for America’s £750 million new embassy in Nine Elms, south London.
He tweeted: “Reason I canceled [sic] my trip to London is that I am not a big fan of the Obama Administration having sold perhaps the best located and finest embassy in London for ‘peanuts,’ only embassy in London for ‘peanuts,’ only to build a new one in an off location for 1.2 billion dollars. Bad deal. Wanted me to cut ribbon-NO!”
His claims were proved to be wrong, as documents showed the decision to sell the previous embassy in Grosvenor Square, central London, was announced by Barack Obama’s predecessor George W Bush.
Mr Khan, who has clashed with the President in the past, said Mr Trump had “got the message” of Londoners.
But the Mayor’s intervention triggered a rebuke from his predecessor in City Hall, Boris Johnson, who accused Mr Khan of being a "puffed up pompous popinjay".
“The US is the biggest single investor in the UK - yet Khan & Corbyn seem determined to put this crucial relationship at risk,” tweeted the Foreign Secretary. “We will not allow US-UK relations to be endangered by some puffed up pompous popinjay in City Hall."i-amphtml-sizer">
The Foreign Secretary's post came in the middle of a regular Westminster briefing by a Number 10 spokesman.
Despite being read the tweet, the spokesman was unable to say whether Mr Johnson spoke for the Government, but promised to "look into it".
Asked if Mr Johnson was speaking for the Government, the spokesman replied: "I'm not aware of the circumstances of the tweet, we will come back."
Before Mr Johnson tweeted, the spokesman was asked if Mr Khan had damaged the so-called "special relationship", replying: "No, the US and the UK are natural resilient strong partners and allies and we do more together than any two countries in the world."
But he said Mrs May would tell Mr Trump he is welcome in London.a href="/lifestyle/london-life/donald-trump-us-embassy-london-vauxhaull-a3738726.html" data-vars-item-name="read more - /lifestyle/london-life/donald-trump-us-embassy-london-vauxhaull-a3738726.html" data-vars-event-id="c29"">> i-amphtml-sizer">

Asked about the PM's views on south London after the president described the embassy's new site as an "off location", the spokesman said: "I think Vauxhall is a vibrant and important part of London and home to many businesses, obviously Apple are moving there headquarters there."
The spokesman added: "A state visit (invitation) has been extended and accepted and we will confirm the details in due course.
"No date was confirmed for any visit, the one you are referring to now.
"The opening of the US embassy is a matter for the US."
The Grosvenor Square embassy, topped by a gilded bald eagle with a wingspan of more than 11 metres, opened in 1960 to a design by Eero Saarinen.
The square has been home to the US since 1938. It was acquired by Qatar for a hotel but the sale, signed off by the Obama administration, raised less than the £500 million first estimated after it was made a Grade II listed building, reducing development potential.
