There was no immediate statement from Johnson, another loud pro-Brexit voice within May's divided government. But she was quick to action, appointing the country's health secretary as Johnson's replacement and chairing a meeting of her new cabinet Tuesday afternoon.
Conservative lawmaker Michael Fallon, an ally of May, dismissed Johnson's "Brexit dream" rallying cry.
She said she and the two departed ministers "do not agree about the best way of delivering our shared commitment to honoring the result of the referendum" in which United Kingdom voters opted to leave the EU. She is nevertheless expected to seek assurances from Trump that the United States is ready to enter negotiations on a bilateral trade agreement.
One of the most sensitive is the border between the Republic of Ireland, an European Union member, and Northern Ireland, which will withdraw as part of the United Kingdom.
On Friday, Davis and the rest of May's fractious Cabinet finally agreed on a plan for future trade ties with the EU.
With less than nine months left until Britain is due to leave the bloc, May is sticking to her plan for a "business friendly" Brexit, facing down hard-line Brexit supporters in her Conservative Party who are livid over her plans to negotiate a "free trade area for goods" with the EU.
"May's efforts to maintain close ties with the European Union following the March 2019 Brexit deadline are perceived by some as a failure to those who voted for divorce", said Miles Workman, an economist at ANZ Bank New Zealand, in a note.
"I welcome the resignations of Boris Johnson MP and David Davis MP from the Cabinet".

By picking Brett Kavanaugh as his latest nominee for the US Supreme Court, Donald Trump has gone for "the safest conservative bet he can find", says Edward Luce in the Financial Times.
"The time is so short, that I don't want to lose time, we have to use time for negotiation with the UK", Barnier added.
Other pro-Brexit Cabinet ministers said they supported May and would not resign.
"I would actually say that she probably went the opposite way".
"I'd have to deliver this". Earlier, Davis told the BBC that he was not encouraging a challenge to May and ruled himself out as a contender if there were one. "That's not a tenable position".
