Trump says he told Theresa May how to do Brexit, but she wouldn't listen.
Now he's threatening to kill a free trade deal with Britain, saying it's impossible if May plans to keep business ties with the EU.
In a bombshell interview with Britain's Sun newspaper on Thursday (July 12), the U.S. President chastised May for ignoring his advice and not making a credible threat to walk away from Brexit talks.
The Sun says the interview was held in Brussels, where Trump hinted at his discontent during the NATO summit earlier this week.
(SOUNDBITE) (English) U.S. PRESIDENT, DONALD TRUMP, SAYING: "The people voted to break it up, so I imagine that's what they'll do but maybe they are taking a little bit of a different route so, I don't know if that's what they voted for." Just hours before it was published, May had made a direct pitch for a deal with Washington at a lavish dinner celebrating Trump's first visit to the country as president.
She's been pushing for a business-friendly Brexit, a plan that would keep Britain in a free trade zone for goods with the EU, but would also mean the UK would have to accept some EU rules.
(SOUNDBITE) (English) BRITISH PRIME MINISTER, THERESA MAY, SAYING: "We deliver that Brexit and we do it in a way that protects jobs and livelihood and meets our commitment to Northern Ireland." Brexit supporters are calling May's plan a betrayal, including lawmakers in her own party.
And Trump's remarks come after a tumultuous few days for May.
Two senior ministers have resigned in protest of her plan.
