United Nations explains why escalator stopped when Trump got on

White House press secretary Karoline Leavitt suggested that someone at the U.N. may have purposely tried to "trip up" the president and first lady Melania Trump.

The United Nations has concluded its one-day investigation into the mysterious halting of President Donald Trump’s escalator Tuesday as he arrived at the U.N. General Assembly.

The accidental culprit? A White House videographer who most likely tripped a safety mechanism.

U.N. secretary general spokesperson Stéphane Dujarric said in a note to reporters that a technician found it was the White House videographer who was unintentionally behind the now-international incident that was caught on video.

“The escalator had stopped after a built-in safety mechanism on the comb step was triggered at the top of the escalator,” Dujarric said. “The safety mechanism is designed to prevent people or objects accidentally being caught and stuck in or pulled into the gearing. The videographer may have inadvertently triggered the safety function described above.”

But the escalator wasn't the only thing that malfunctioned for Trump during his visit to the U.N.
