"There were also a few times, FYI, where I just started talking, being like, 'Hey, I want to add something there,' and my mic was not on," the tech entrepreneur said while speaking to supporters after the event.

"And it's this sort of thing where, it's not like if you started talking, it takes over the [conversation]. It's like I was talking, but nothing was happening. And it was like, 'Oh f---.' So that happened a bit too."

The hashtag "#LetYangSpeak" was trending on Twitter Friday afternoon.

The allegation comes after an analysis by The Hill shows Yang had the least amount of speaking time of all the 20 candidates who participated in the two nights of debates that took place Wednesday and Thursday.
