Following another objection, Costello let out an audible breath. Judge Merchan then sent the jury out of the courtroom.
"I'd like to discuss proper decorum in my courtroom," he admonished Costello. "If you don't like my ruling, you don't give me side-eye and you don't roll your eyes. Do you understand that?"
Costello said he understood.
Then Merchan abruptly said: "Are you staring me down?"
A furious Merchan then ordered the entire courtroom cleared out.
