"Hold my calls" apparently didn't apply to Donald Trump in court on Thursday.
People in the courtroom watched as he started talking on a phone at the defense table before the judge entered the room.
The former president was on the phone for about 30 seconds before his lawyers came over and put it away, the Associated Press reported.
Cell phone usage is generally prohibited in New York courtrooms.
Two of the seven people who have been seated on the jury were dismissed on Thursday.
One was released after expressing concerns that part of her identity was made public by the media, CNN reported.
Juan Merchan said she felt "afraid" by the information being released.
He then ordered the media to not report on any current or past employers of potential jurors.
"We just lost what probably would've been a very good juror," Merchan said. "There's a reason this is an anonymous jury."
A second seated juror was dismissed after prosecutors had said they found information about a possible arrest of the juror for tearing down political posters.
Two additional jurors have since been selected for the trial, taking the spots of the two previously removed jurors, according to ABC.
With seven jurors now seated, 11 more people will need to be seated.
They will make up the jury and the alternates who will be present for the trial but not take part in jury deliberations unless they replace someone who is removed during the trial.
As the court breaked for lunch, Trump complained about the temperature in the courtroom.
He reportedly turned to reporters and asked, "Is it cold enough?"
One of Trump's attorneys had earlier asked if the courtroom could be made any warmer.
Merchan said he would rather be a little cold than sweat, according to CNN.
