U.N. and Secret Service investigate possible sabotage of Trump's escalator malfunction

During his speech at the U.N. General Assembly, President Trump experienced a malfunctioning escalator and teleprompter, which he and the White House suggested might have been intentionally sabotaged, though the U.N. indicated the escalator stopped due to a safety mechanism triggered by a videographer from the U.S. delegation. The incident was used by Trump to criticize the U.N., and the Secret Service is investigating the matter.
