From a TV pool reporter at the event:
After 10 minutes of a shoving match between the US and Russian side – with each side trying to negotiate getting inside the spray. Wranglers attempted to get everyone to form lines as everyone tried to shove up to the front. Lots of elbowing, yelling and shoving in both Russian and English by security, press and delegations. The Swiss officials tried to quiet everyone and form lines – it did not work.
