The European Union Foreign Policy Chief Federica Mogherini Monday complained that Europe is having a hard time contacting U.S. authorities in an effective manner.
Answering Euronews' question on how the EU "keeps up dialogue with the current U.S. administration which relies on Twitter diplomacy", Mogherini said the bloc is in contact with the U.S. "on all levels and with one voice."
"Sometimes I think of Henry Kissinger's joke: ''Who do I call if I want to call Europe?'. Now the U.S. has Europe's number but it's our turn to ask 'Who do we call if we want to call Washington?'! But we often talk and we're still working well together on a number of issues," Mogherini said.
Since U.S. President Donald Trump's election, the EU and the U.S. have disagreed on issues ranging from the Iran nuclear deal, climate change and trade.
Washington's traditional allies in Europe were at first cautious in their approach to Trump, hoping he would mellow as he grew into the Oval Office role.
But they were outraged with Trump's intention of withdrawing from the Iran deal, and united in their response.
