When in Brussels

Looks like he shortened up his necktie to a European standard.

Donald Trump is said to have told European Union leaders he is worried Americans may lose jobs as a result of Britain leaving the EU, in what would amount to an extraordinary U-turn by the US president.

The Guardian made a typo. It should read: "what would amount to another U-turn by the US president."

The president was a cheerleader for Brexit, describing June’s vote as a “beautiful, beautiful thing”. After meeting Theresa May at the White House earlier this year, he claimed Brexit would be a “wonderful thing” for Britain.

He also suggested in the past that other countries might follow Britain out of the 28-nation bloc, although in recent weeks he has publicly revised that view, claiming the EU has been doing a “better job” of late.

In the moment. Strictly a man in the moment, without a rudder, and subject to every whim or whoever he talked to in the last ten minutes.

It was reported that Trump had asked the German chancellor [Angela Merkel a private conversation last month] 10 times if he could negotiate a trade deal with Germany. Every time Merkel reportedly replied: “You can’t do a trade deal with Germany, only the EU.” “On the 11th refusal, Trump finally got the message: ‘Oh, we’ll do a deal with Europe then,’” an unnamed German politician was quoted as saying.

He catches on quickly.

This suggests the Transatlantic Trade and Investment Partnership (TTIP) trade deal between the EU and US, shelved after Trump’s election victory, could be revived.

You mean the deal he ranted against in the campaign to win votes?

...but hey, do what you want...you will anyway.
