A tweet from the official account for the Auschwitz Memorial read: “Everyone has the right to personal reflections. However, inside a former gas chamber, there should be mournful silence. It’s not a stage.”
There is a clear and explicit sign outside the chambers which asks visitors to “maintain silence”, then adds: “Remember their suffering and show respect for their memory.”
During the clip, Mr Higgins is seen walking around the camp, comparing the horrors of the Nazis to the threat of global terrorism today.
He said: “It’s hard to walk away from gas chambers, ovens, without a very sober feeling of commitment, unwavering commitment, to make damn sure that the United States of America is protected from the evils of the world.”
