Fox News reports that the Manhattan District Attorney's Office has received a package containing suspicious white powder. 

This is the same office that is led by Alvin Bragg. Bragg is the district attorney who is deciding whether or not to indict former President Donald Trump regarding alleged nondisclosure payments Trump made in 2016 to adult film star Stormy Daniels.

Trump denies any wrongdoing, and he maintains that Bragg, in pursuing him, is politically motivated.

What we know:

The package containing the suspicious white powder was delivered, according to Fox, to the mail room of the building, located in New York City, in which the Manhattan District Attorney's office is located.

The Manhattan District Attorney's office, though, is not the only office located in the building. Several other offices are located in the building. And, the building also happens to be where the grand jury has been meeting with regard to the possible Trump indictment.

That being said, it does appear that Bragg was the target of the package.

A note was included with the package. And, according to Fox, "a law enforcement source confirmed" that the note said, "Alvin – I’ll kill you."

More details

An investigation is underway. It has been determined that the package and its contents were "non-hazardous."

The Manhattan District Attorney's office put out a statement, saying that the package "was immediately contained and that the NYPD Emergency Service Unit and the NYC Department of Environmental Protection determined there was no dangerous substance."

At the time of this writing, it does not appear that any real progress has been made in tracking down the source of the package.

NBC News reports:

Markings on the envelope indicate it was mailed from Orlando, Florida, earlier this week, the sources said. It was postmarked on Tuesday, the sources said.

A tough week

After the incident, Bragg, according to NBC, disseminated an email to his office personnel in which he acknowledged that it has been a tough week for the office.

Bragg, in that email, is reported as saying, "I know it hasn’t been easy" with all of the "press attention and security around our office." Bragg is further reported to have thanked everyone for their "strength and professionalism during this time." He also said that "we will continue to apply the law evenly and fairly."

Trump, for his part, has not commented on the package that was sent to Bragg's office.
