Authorities have arrested Jacob Schwartz, a New York City employee and president of the Manhattan Young Democrats, for allegedly possessing child pornography.

The NYPD Computer Crimes division began an investigation in March and Schwartz surrendered his computer. The detectives “found more than 3,000 images and 89 videos depicting girls as young as 6 months old performing sex acts on adult men.”

Authorities said Schwartz downloaded the material from the internet.

Schwartz had enjoyed a rise in New York City as a Democrat activist. From The New York Post:

Jacob Schwartz is the president of the Manhattan Young Democrats and the downstate region vice president of the New York State Young Democrats.

But his name and photo were scrubbed from both groups’ Web sites after The Post broke the news of his arrest.

A statement from the Manhattan Young Democrats said the organization was “shocked” by the allegations against Schwartz, and added that he was “no longer a member of the board, and an interim president is now in place.”

A photo posted last year on Twitter shows him posing with Robby Mook, then the campaign manager for Hillary Clinton’s disastrous presidential campaign.

He “founded the New Democratic Alliance and worked for the Obama presidential campaign in 2012 as a field organizer in Lehigh Valley, Pa.” He also founded the nonprofit group Common Climate, which he served as the executive director of environmental education.

Schwartz worked as a “computer programmer analyst in the city Department of Design and Construction.” The department has terminated his access while City Hall and the Mayor’s office has denied a connection to him. From CBS New York:

“Obviously, these are extremely serious allegations. This is a junior-level agency employee with no connection to the Mayor or City Hall,” Mayor’s Office Deputy Press Secretary Melissa Grace said in a statement. “He is being terminated immediately, and the agency is cooperating with investigators.”
