I've long told my classes, "If you know how the system works, you'll know how to work the system." And the way Washington really works is through connections and conversations and perseverance.
The New Yorker has an excellent example this week, an article by historian Kai Bird about the effort to nullify a denial of a security clearance for the leader of the Manhattan Project that built the atom bomb, Robert Oppenheimer.
Bird and Martin Sherwin, who had co-authored a book about Oppenheimer, tried to get a DC law firm to take up the case, only to be blocked by a partner whose father had chaired the panel that punished Oppenheimer. Later they used Hill connections from long ago to try to get the Obama Administration to reconsider the matter. A legendarily effective Senate staffer, Tim Rieser, got his boss and other Senators to sign a letter to the Secretary of Energy, who has jurisdiction over the weapons labs and thus their security procedures. Unsuccessful at that time, they renewed their effort in the Biden administration, got additional letters from former officials, and finally favorable action by Secretary Granholm.
People mattered, both for and against Oppenheimer's case. Organizations mattered: DOE officials were reluctant to revisit the issue or make legal rulings. The process mattered: connecting the advocates with people empowered to act. What a neat story, especially with a happy ending.
