The white powder was in a USPS envelope. It was been transported to a city lab for further analysis, the NYPD spokesperson said.

Neither the office nor the courthouse was evacuated, the spokesperson said.

The scare comes after Trump took to Truth Social to predict “potential death & destruction” if a grand jury votes to indict the former president for his alleged role in a 2016 hush money payment to porn star Stormy Daniels.

The grand jury was not sitting Friday since it typically only hears evidence on Mondays, Wednesdays and Thursdays. The panel took a two-day break this week after a flurry of witnesses, leading some to speculate the case was in trouble. But legal experts told POLITICO there were more likely routine reasons for the pause.

Last week, Bragg told office employees in an email that “we do not tolerate attempts to intimidate our office or threaten the rule of law in New York.”

“Our law enforcement partners will ensure that any specific or credible threats against the office will be fully investigated and that the proper safeguards are in place so all 1,600 of us have a secure work environment,” Bragg wrote.

That message followed an earlier warning by Trump that his supporters should “Protest, take our nation back!” if he was arrested in connection with Bragg’s probe.
