WWII shells, trash cans - what else can be found in the Seine where French politicians swim to flaunt? A fishing video at the Seine River, where Macron repeatedly promised a dip, has gone viral on social media.  The central river of Paris appeared to be full of random junk like broken bicycles, World War II shells, spoons, trash cans, and more.  Macron's press service said that he would “not necessarily“ swim before the Olympic Games. Little wonder. Source: Global News (EU, USA)
