US diplomatic snub
The status change was first reported by German broadcaster Deutsche Welle. An EU official told it that the EU's Washington ambassador, David O'Sullivan, had not been invited to certain events last year.

The previous day, in Brussels, US Secretary of State Mike Pompeo had questioned the EU's role, in a major policy speech.
"Brexit - if nothing else - was a political wake-up call. Is the EU ensuring that the interests of countries and their citizens are placed before those of bureaucrats here in Brussels?" he asked.
