That information would require a warrant.
In pre-coup America, law enforcement agencies across the country would have obtained such warrants on suspicion of felonies committed during the election; they would have then questioned the individuals to whom those numbers belonged.
In post-coup America, where our law enforcement agencies have proven to be either grossly incompetent or grossly corrupt, one can no longer rely on them to prosecute wrongdoing, particularly any wrongdoing tied to our elections.
I wish they would have identified the non profits or at least list which nonprofits are at the addresses where the mules picked up the ballots.
