"If they do a deal like that, we would be dealing with the European Union instead of dealing with the UK, so it will probably kill the deal," Trump reportedly said in an interview in the Sun newspaper published Friday.
POTUS claims Theresa May's plans for soft Brexit will end any hopes of trade deal with USA.
Also suggests Boris Johnson, who quit PM May's cabinet last week, would be a better leader than Theresa May.
Comments came at start of three-day tour of UK.
PM May's goal here was to impress Trump. She needed to use Trump's visit to push for trade deal with US post-Brexit. Doing so would have yielded local business confidence and leverage in negotiations with EU.
President Trump seemingly gave Theresa May the cold shoulder in her time of need.
