Doxxer Jackson Cosko Has Ties to Dianne Feinstein – Possessed Senate Data – And Now the DOJ May Hide Details of Breach

Doxxer Jackson Cosko

Last October, Capitol Police arrested 27-year-old Jackson Cosko of D.C. for “allegedly posting private, identifying information (doxxing) about one or more United States Senators.”

Jackson Cosko was charged with Making Public Restricted Personal Information, Witness Tampering, Threats in Interstate Communications, Unauthorized Access of a Government Computer, 2nd Degree Burglary & Unlawful Entry.

Jackson Cosko even threatened a political aide who caught him, “I own EVERYTHING. If you tell anyone I will leak it all. Emails signal conversations gmails.”


Many Republicans on the Senate Judiciary had their home addresses and phone numbers published on their Wikipedia pages last year during the Kavanaugh confirmation hearings.

Shortly after Lindsey Graham went off on Senate Democrats for destroying Kavanaugh’s life in order to derail his confirmation, Republicans were doxxed.

The victims included Republican Senators Mike Lee, Orrin Hatch of Utah and Lindsey Graham.

Democrat Jackson Cosko was a “cyber-security graduate student,” according to his LinkedIn page and apparently comes from a very wealthy and politically connected family with ties to Senator Dianne Feinstein (D-CA).

Because of Jackson Cosko’s elite family status and wealth, Democrat connections and special treatment by DOJ prosecutors, the American public may never know the truth.

According to investigative reporter Luke Rosiak, Jackson Cosko was in possession of troves of information, including Senate data so his threats certainly did not seem like a bluff.

However, government prosecutors signaled this week that they may give Cosko a plea deal that would prevent the details of the case from being made public.

The Daily Caller reported:

The suspect’s father, Greg Cosko, is the CEO of Hathaway Dinwiddie, a massive construction company that built a university building named after Feinstein’s husband. He serves on the board of San Francisco State University alongside Willie Brown, the California politician who said he helped make the career of California’s other Democratic senator, Kamala Harris, with an illicit affair.

As former chairman of the San Francisco Chamber of Commerce, Greg Cosko hobnobbed with then-House Minority Leader Nancy Pelosi, Feinstein and others. The elder Cosko’s adult son appears to have made inroads in Washington via an internship with Feinstein.

Jackson Cosko appeared to have absconded with vast troves of data months before the confirmation hearing, and even allegedly had Senate letterhead. Even after he was caught, he continued to make threats, Hogan said.

At December and January court dates, Hogan barred The Daily Caller News Foundation from the courtroom as lengthy proceedings went on, even though Cosko’s mother was allowed to stay. The judge assured that what was said would become public eventually.

But this week, prosecutors said they intend to resolve the case with a plea deal, likely shielding the extent of the alleged breach of the Senate forever. They canceled a court date set for Thursday, writing, “The parties are in discussions to resolve the case and require additional time for that purpose.”

Asked if that meant the evidence of major crimes discussed behind closed doors would never be unsealed, prosecutor Tejpal S. Chawla said “we’ll see.”
