BERLIN, June 1 (Xinhua) -- Bernie Sanders, a United States Democrat and Junior Senator, took to the stage on Wednesday in Berlin at a student speech to strongly criticise President Donald Trump.
Sanders was in Berlin to launch the German version of his book "Our revolution" and was speaking at the Free University of Berlin.
Sanders spoke about the important relationship between the United States and the EU, saying that "notwithstanding Trump", the "majority of Americans were in agreement with him."
He also chided Trump for criticizing a "longstanding ally" after tweeting that Germany is not adhering to its NATO military obligations early this week, as well as on several other high-profile occasions.
Sanders went further, and denounced the decision to walk away from the 2015 Paris Agreement on climate change, telling the crowd that it would be a "horrific mistake" to permanently withdraw from the agreement.
He told the crowd in Berlin "do not think that the American people are turning their backs on this."
Sanders, who was a Democrat nominee for the 2016 U.S. Presidential elections, is one of the most outspoken critics of President Trump prior to and since he was inaugurated.
