In the lawsuit Unity08 v FEC before the DC District Court, Unity08 provided a Notice of Amended Address, filed 1/12/07:
2600 Virginia Avenue, NW, Suite 514, Washington, DC 20037
This is part of the Watergate complex.
This same address, right down to the suite number, is also claimed as an address for the law firm of Franch, Jarashow, Burgmeier & Smith, as well as an organization called the Thoreau Group. I’ve called both entities and verified that they have office space there, and share the space with others. Is this a functional space?
