Trump demands inquiry over UN 'triple sabotage' after escalator and teleprompter mishaps

Donald Trump has demanded an investigation into what he called a "triple sabotage" during his visit to the United Nations General Assembly on Wednesday.

In a post on social media, the US president referred to an escalator abruptly stopping as he and First Lady Melania Trump stepped on, a teleprompter malfunctioning during his speech, and an audio issue in the auditorium.

A UN official said the sound system was designed to allow people to hear translated speeches through earpieces.
