Wading in again to his hosts' domestic politics, Trump says of Johnson, "He's a friend of mine," adding he may also meet with another pro-Brexit politician, Nigel Farage, during his visit. Trump is also firing back at London mayor Sadiq Khan, who called the U.S. leader a "global threat" ahead of his trip. He said he has no interest in meeting, saying, "No, I don't think much of him."
Trump adds, "He's the twin" of New York City mayor Bill de Blasio, "except shorter."
President Donald Trump is heading back to Europe, where his previous visits have strained historic friendships and insulted his hosts.
This time, he faces an ally in turmoil, Britain, and a global call to renew democratic pacts.
The agenda for Trump's weeklong trip is both ceremonial and official: a state visit and an audience with Queen Elizabeth II in London, D-Day commemoration ceremonies on both sides of the English Channel and his first presidential visit to Ireland, with a stay at his coastal golf club.
Trump will arrive at a precarious moment, as he faces a fresh round of impeachment fervor back home and uncertainty on the other side of the Atlantic.
Trump is to leave Washington on Sunday and arrive in London on Monday morning for a two-day stay.
