New York: US President Donald Trump suffered a number of awkward tech difficulties during his visit to the United Nations headquarters, including a broken escalator and a faulty teleprompter. The day was beset with technical problems for him after it was reported that UN workers had been overheard joking about switching off the power to an escalator. According to The Times, “figures inside the UN” were swapping ideas of pranks they could pull to highlight budget holes in the organisation after the Trump administration withheld funding. Among them was stopping the power to the escalators and lifts. On Tuesday (Wednesday AEST), the US president and first lady Melania Trump were left standing confused on an escalator after it stopped as they stood on it at the entrance of the UN New York headquarters.
