The US President hit out after Theresa May has accepted an offer from the leaders of the remaining 27 EU countries to delay Brexit until October 31. Mr Trump also issued a thinly-veiled threat to shake-up America's trading relationship with the EU amid fears he is set to slap import tariffs on a wide range of goods, as reported by Express.Co.
He tweeted: "Too bad that the European Union is being so tough on the United Kingdom and Brexit.
“The EU is likewise a brutal trading partner with the United States, which will change. Sometimes in life you will have to let people breathe beforeit all comes back to bite you."
