Watch: VP Harris Goes Viral for Word-Salad Moment Where She Just Can't Stop Saying 'The Passage of Time' via @WestJournalism [westernjournal.com]
In public speaking, that would be called a Verbal Pause. When a person is trying to deliver a speech and they have a momentary “brain cramp” or they suddenly go blank, one method of trying to keep the audience’s attention while they regain their thoughts is to repeat the last remembered thought. It the first repetition doesn’t provide enough time to regain the train of thought, repeating it again with a different emphasis as if it were an important point that needs to really Sino in for the hearer of the speech.
At some point, if the train of thought doesn’t return, it’s time to give it up and move on or you’ll end up looking like a Harris.
