WikiLeaks released Thursday a massive trove of what it claims are documents from an ongoing German parliamentary probe into the country’s relationship with the National Security Agency (NSA).

The site claims its 90-gigabyte cache contains over 2,400 files from an investigation into how Germany’s chief intelligence agency partnered with the NSA for mass surveillance without informing much of the government. The inquiry launched in 2014.

“A number of the documents show how intelligence agencies find ways to work around their own government,” reads a statement accompanying the release.

The files are available for download through the torrent system of file sharing.

In the website statement, WikiLeaks head Julian Assange chided the German government for launching the inquiry without the testimony of former NSA contractor Edward Snowden, whose documents ultimately provided its foundation. Having leaked U.S. secrets, Snowden is still a politically difficult figure for many nations to cooperate with.

“This substantial body of evidence proves that the inquiry has been using documents from Mr. Snowden and yet it has been too cowardly to permit him to testify. Germany can not take a leadership role within the EU if it's own parliamentary processes are subservient to the wishes of a non-EU state," he wrote.

With the top economy in Europe, Germany is generally considered to have a leadership role within the European Union.
