Witnesses stated they saw it. The picture being circulated is an example. Some people ran with that being a shot from there.

So "hoax"? Not quite, but granted, there is no evidence as of yet.

Okay so we're down to several references to Aushwitch then. Plus the fact that the groups involved have a well documented connection.

No. Someone confirmed the picture as being from a different event. That the '6 million' shirt was at the Capitol is proven false.

We're down to one Auschwitz reference. One too many. But still nothing like 'actual Nazi flags'.

Again: how much research did you do?
