Dennis Montgomery is/was a contractor for US intel, most notable for developing the HAMR program, aka "The Hammer."
Hammer is a very sophisticated, robust, parallel program (on surveillance).
Court documents on this issue of US intel spying with this program have various case numbers, due to the case & its issues covering different regions such as Nevada, Arizona, Florida, & DC.
The most notable court document I came across is attached here due to the details of not just spying but on whom was spied:
