Brookings played a large role in pushing the Russian collusion narrative, hiring a variety of experts who then populated media outlets like MSNBC and CNN stating confidently that Trump was clearly incriminated in a series of dubious criminal acts. While no such crimes were ever charged, let alone prosecuted, Brookings maintained a deep bench of enabling experts like Susan Hennessey (now a national security adviser in the Biden Administration), Ben Wittes (who defended James Comey in his leaking of FBI memos) and Norm Eisen (who then become counsel in the Trump impeachment effort). This included the Brookings site, LawFare, which ran a steady stream of columns on how Trump could be charged for crimes ranging from obstruction to bribery.
However, that type of media cross-pollination is common. What is most surprising is how the indictment seems to map out roads that keep leading back to Brookings.
