The Justice Department revealed on Wednesday that it had obtained a new search warrant to access the contents of attorney John Eastman’s phone, which it seized from the pro-Trump lawyer last month before transporting it to a lab in Virginia.

The development, filed in court via Assistant U.S. Attorney Thomas Windom, came in response to a legal effort by Eastman to block investigators from “rummaging” through his files. The Justice Department had indicated that it would obtain a warrant that would limit investigators’ access to “evidence of specific federal crimes or specific types of material.”

Windom indicated in the filing that the new warrant — dated July 12 — included a “filter protocol” to prevent investigators from accessing privileged material, and that the details of that process had been communicated to Eastman’s attorneys.
