Tech firm is fighting a federal order for data on visitors to an anti-Trump website

A Los Angeles-based tech company is resisting a federal demand for more than 1.3 million IP addresses to identify visitors to a website set up to coordinate protests on Inauguration Day — a request whose breadth the company says violates the Constitution.

“What we have is a sweeping request for every single file we have” in relation to DisruptJ20.org, said Chris Ghazarian, general counsel for DreamHost, which hosts the site. “The search warrant is not only dealing with everything in relation to the website but also tons of data about people who visited it.” The request also covers emails between the site’s organizers and people interested in attending the protests, any deleted messages and files, as well as subscriber information — such as names and addresses — and unpublished photos and blog posts that are stored in the site’s database, according to the warrant and Ghazarian.
