Yar! I beleive this to be a notable:

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.

At the state funeral for the late President George HW Bush, on 5 December, the EU's ambassador was not called up in the usual chronological order, from the longest-serving to the newest ambassador, "but he was called up as the last person", the EU official said.

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.
