The joint presser comes just hours after leaked excerpts from Trump's explosive interview with the Sun newspaper saw the president harshly criticizing May's recently unveiled plan for Britain's exit from the European Union, known as Brexit.
Trump complained to the tabloid that May ignored the advice he gave her about how to negotiate an exit from that international organization. And he added that if May follows through with her plan, a bilateral trade deal with the U.S. could be compromised.
“If they do a deal like that, we would be dealing with the European Union instead of dealing with the U.K., so it will probably kill the deal,” Trump told the tabloid.
