Washington’s revolving door kept spinning this week as the Drug Enforcement Administration’s recently departed second-in-command returned for a new stint with the high-powered consulting firm where he previously advised Purdue Pharma and a drug distributor fighting sanctions over a deluge of suspicious painkiller shipments. Louis Milione retired from the DEA a second time this summer amid reporting by The Associated Press on potential conflicts caused by his prior consulting for the pharmaceutical industry. Less than three months later, Milione again landed a plum job at Guidepost Solutions, a New York-based firm hired by some of the same companies he had been tasked with regulating when he returned to the DEA in 2021 as Administrator Anne Milgram’s top deputy.
