For many years, Jeffrey Sachs would appear on mainstream corporate media networks and be quoted in the major publications. Then he appeared on Bloomberg TV and, in an interview with Tom Keene, said that the US was behind blowing up the Nord Stream 2 pipeline. Keene's reaction was priceless. It was a textbook case of someone going against the approved "narrative" and Keene didn't know what to do.
I don't think Sachs has appeared on any of the mainstream corporate media outlets since. Total black eye for Bloomberg and the rest of the media.
