According to Haralabos Voulgaris, he cold four-bet out of the blinds after two players had raised ahead of him. One of the players called off all in, and the three-bettor was contemplating his move. Voulgaris commented that the player was going to get to see his hand regardless of his decision, and one of the other players apparently asked for the floor to be called because he didn't think Voulgaris should be talking about his hand with players still in the pot.
We didn't see or hear what the supervisor had to say, but we did hear the aftermath.
"I paid $10,000 to play a poker tournament, I want to talk," Voulgaris said loudly, eliciting chuckles from players at nearby tables. "If I can't talk, you can just take my chips and I'll go home."
Voulgaris is still sitting behind his big stack at Table 2, so it seems he's been allowed to talk.
