That's not on the schedule, but the president makes his own schedule. "Very supportive. I maybe will speak to him when I get over there".
Mr Trump said he had not spoken with Mrs May, adding: "Boris Johnson is a friend of mine".
US Ambassador to Britain Woody Johnson on Wednesday rowed back on President Donald Trump's comment that Britain was in "turmoil" because of Brexit-linked political upheaval.
On Tuesday, the president described Johnson as a "friend" who had been "very nice to me, very supportive", even though when Trump suggested in 2015 London had police no-go zones, Johnson, then the capital's mayor, quipped he feared going to NY because of "the real risk of meeting Donald Trump".
The president said Mrs May "can't walk away" from exit talks with the European Union, though suggested she could use other methods to secure a good deal.

"Next week is another big dramatic week, we will have a resignation speech from Boris Johnson and we will have some crucial amendments being voted on in the House of Commons".
"We're extremely confident in the ability of the United Kingdom to plow through this issue with Brexit and move on", he said.
"I don't think it provides a solution to Brexit but I think it is something that can provide an input into the negotiations".
"Whatever the decision the Queen decides to take about whether to invite him to tea or not, and what advice the Prime Minister gives on that, is between them, I don't know what went on. So I think that symbolizes how he considers the importance of her leadership in this country right now".
He went on to say Mr Johnson, who quit as foreign secretary over the Chequers' plan, was "a great representative for your country".
"But personally, I don't think we should have been rolling out the red carpet for Donald Trump".
