President Donald Trump on Wednesday demanded an "immediate investigation" into what he claimed was "triple sabotage" during his United Nations visit on Tuesday, citing a stopped escalator and a teleprompter that wasn't working.

Axar.az informs, citing ABC news, "A REAL DISGRACE took place at the United Nations yesterday — Not one, not two, but three very sinister events!," he posted on his social media platform, saying he was sending a letter to U.N. Secretary-General António Guterres.

"First, the escalator going up to the Main Speaking Floor came to a screeching halt. It stopped on a dime. It's amazing that Melania and I didn't fall forward onto the sharp edges of these steel steps, face first. It was only that we were each holding the handrail tightly or, it would have been a disaster," he wrote.

"This was absolutely sabotage, as noted by a day's earlier "post" in The London Times that said UN workers "joked about turning off an escalator." The people that did it should be arrested!" he continued.

After complaining about a second issue -- how his teleprompter didn't work for the first 15 minutes of his address -- he claimed the audio in the General Assembly Hall has been turned off.

"And third, after making the Speech, I was told that the sound was completely off in the Auditorium where the Speech was made, that World Leaders, unless they used the interpreters' earpieces, couldn't hear a thing," he wrote. "The first person I saw at the conclusion of the Speech was Melania, who was sitting right up front. I said, "How did I do?" And she said, "I couldn't hear a word you said." This wasn't a coincidence, this was triple sabotage at the UN. They ought to be ashamed of themselves."

The United Nations issued a statement about the incident, saying that the escalator stopping might have been triggered by a safety feature as a videographer was standing backward on the escalator, ahead of the president, while trying to film him.

"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," the U.N. statement said.
