I am watching her speak Live on CNN right now, on a serious topic. As it says at the bottom of the screen "Melania Trump Makes Rare Appearance at State Dept./First lady presenting International Women of Courage Awards".
Though she is clearly using a prepared script, she is stumbling on some words and her accent has never sounded so heavy. Yet there is a sincerity to her delivery that it comes across that this is one issue she cares about.
