How to stop a virus, how to take a census, how to determine if some foreign country is seeking to obtain a nuclear weapon or if North Korean missiles can reach Kansas City: these are enduring technical problems. The people appointed by a newly elected president to solve these problems have roughly 75 days to learn from their predecessors. After the inauguration, a lot of deeply knowledgeable people will scatter to the four winds and be forbidden, by federal law, from initiating any contact with their replacements.

A month after the election Thomas Pyle, a former lobbyist for Koch Industries, arrived for a meeting with Energy Secretary Ernest Moniz, Deputy Secretary Sherwood-Randall, and Knobloch. Moniz is a nuclear physicist, then on leave from M.I.T., who had served as deputy secretary during the Clinton administration and is widely viewed, even by many Republicans, as understanding and loving the D.O.E. better than any person on earth. Pyle appeared to have no interest in anything he had to say. “He did not seem motivated to spend a lot of time understanding the place,” says Sherwood-Randall. “He didn’t bring a pencil or a piece of paper. He didn’t ask questions. He spent an hour. That was it. He never asked to meet with us again.”

Pyle then vanished from the scene. He was replaced by a handful of young ideologues who called themselves “the Beachhead Team.” “They mainly ran around the building insulting people,” says a former Obama official. “There was a mentality that everything that government does is stupid and bad and the people are stupid and bad,” says another.

Across the federal government the Trump people weren’t anywhere to be found. Between the election and the inauguration not a single Trump representative set foot inside the Department of Agriculture, for example. The Department of Agriculture has employees or contractors in every county in the United States, and the Trump people seemed simply to be ignoring the place. Where they did turn up inside the federal government, they appeared confused and unprepared. A small group attended a briefing at the State Department, for instance, only to learn that the briefings they needed to hear were classified. None of the Trump people had security clearance—or, for that matter, any experience in foreign policy—and so they weren’t allowed to receive an education.

The one concrete action the Trump transition team took before Inauguration Day was to clear the D.O.E. and other federal agencies of people appointed by Obama. This was a loss. A lunch or two with the chief financial officer might have alerted the new administration to some of the terrifying risks they were leaving essentially unmanaged. Roughly half of the D.O.E.’s annual budget is spent on maintaining and guarding our nuclear arsenal, for instance. Two billion of that goes to hunting down weapons-grade plutonium and uranium at loose in the world so that it doesn’t fall into the hands of terrorists. In just the past eight years the D.O.E.’s National Nuclear Security Administration has collected enough material to make 160 nuclear bombs. The department trains every international atomic-energy inspector; if nuclear power plants around the world are not producing weapons-grade material on the sly by reprocessing spent fuel rods and recovering plutonium, it’s because of these people.
