On Thursday, President Trump appeared to push Montenegro's prime minister, Dusko Markovic, aside before a photo op at the NATO summit in Brussels.

"He needs to be in the front; he's the leader," Reiman said as she watched the footage. "Everybody else just needs to move out of the way and then he goes and adjusts [his jacket], and he lifts his chin in superiority."
