Angry Trump supporters have swamped the Manhattan DA's office with hundreds of angry calls spewing racial slurs and parroting Trump's rhetoric

• The Manhattan attorney's office investigating Donald Trump has been "inundated" with calls from angry supporters.
• The callers have been parroting Trump's rhetoric and hurling racial slurs against DA Alvin Bragg.
• In recent days, the Manhattan DA's office has been the victim of several death threats.

Since Donald Trump falsely predicted his New York arrest more than a week ago, the Manhattan district attorney's office investigating the former president has been completely "inundated" with angry callers parroting his rhetoric against the prosecutor and hurling racial slurs, Insider has learned.

The office of Manhattan District Attorney Alvin Bragg has received more than 1,000 phone calls and emails from Trump supporters, including multiple death threats, as a potential indictment looms against Trump over allegations of a hush-money payment to porn star Stormy Daniels, a source familiar with the matter told Insider.

Callers have made "threatening" and "racially-charged" comments against Bragg — a Democrat and Manhattan's first Black district attorney — and, like Trump and other Republican backers, have accused the DA's office of carrying out a "witch-hunt" and the "political persecution" of Trump, Insider has learned.

"These people are living, breathing mouthpieces" of Trump, a source said of the callers.

Some callers have angrily repeated right-wing conspiracy theories amplified by Trump about Bragg being a "puppet" funded by billionaire Jewish philanthropist George Soros, while other callers have called Bragg the N-word, according to the source.

In recent days, the Manhattan DA's office has been the victim of several death threats — some directly about Bragg — in the form of calls, letters, social media posts, and emails, Insider has learned.

Last Friday, an envelope of ultimately harmless white powder was sent to Bragg at the office building where the ongoing grand jury investigating Trump sits. The envelope reportedly contained a note addressed to Bragg that read: "ALVIN: I AM GOING TO KILL YOU!!!!!!!!!!!!!"

The New York Police Department is still investigating and no arrests have been made yet, an NYPD spokeswoman told Insider on Monday.

Trump claimed on his social media app, Truth Social, on March 18 that he would be arrested in the hush-money case on Tuesday of last week, but that did not happen.

Trump has ramped up his attacks against Bragg and his office as a grand jury continues to investigate whether to indict Trump over his alleged role in indirectly paying Daniels $130,000 in the days before the 2016 election to keep quiet about an alleged affair.

In his social media posts, Trump has called on his backers to "protest" and "take our nation back," threatened "potential death & destruction" in response to a possible indictment against him and mocked calls for peaceful demonstrations.

Last week, Trump called for Bragg's removal in a Truth Social post, described him as "a danger" to the country, and accused him in an all-caps rant of being a "SOROS BACKED ANIMAL WHO JUST DOESN'T CARE ABOUT RIGHT OR WRONG."

"THIS IS NO LEGAL SYSTEM, THIS IS THE GESTAPO, THIS IS RUSSIA AND CHINA, BUT WORSE. DISGRACEFUL!" Trump spouted off.

In a since-deleted post, Trump also shared a photo of himself holding a baseball bat, ready to swing, next to Bragg.

Even Trump's own defense attorney admitted that the post was "ill-advised."

"I'm not his social media consultant," Trump lawyer Joe Tacopina told NBC's Chuck Todd on "Meet the Press" on Sunday. "I think that was an ill-advised post that one of his social media people put up, and he quickly took down when he realized the rhetoric and photo that was attached to it."

Meanwhile, Bragg said in an internal memo last Friday following reports about the envelope with white powder that some staffers have received "offensive or threatening phone calls or emails directly" to their desk lines and added that employees' safety "is our top priority."

"I am very sorry that you have had to endure these distressing disruptions to your workdays," Bragg wrote in the memo in which he praised staffers for their "strength and professionalism during this time."

The DA continued, "We will continue to apply the law evenly and fairly, which is what each of you does every single day."

Democratic New York Rep. Adriano Espaillat and community leaders on Monday held a press conference condemning the "Republican-backed racist, and hateful attacks targeting" Bragg.

Espaillat said that members of the Republican party should call out Trump over his recent attacks and commentary.

"For a so-called party of law and order, many of them are not behaving in that fashion," Espaillat said, adding, "We will not have another January 6th in New York City."
