BRUSSELS – The leader of NATO’s newest member state had a first-hand lesson in power dynamics at the alliance summit in Brussels, when he found himself pushed out of the way by US President Donald Trump.

The video of the interaction shows Trump grabbing the shoulder of Prime Minister Duško Marković of Montenegro and pushing him aside so he could get through to NATO Secretary-General Jens Stoltenberg. Trump then adjusts his jacket and answers a question from Lithuanian President Dalia Grybauskaite, as the flustered Marković smiles and nods behind them.
