uhm... Off the top of my head: Revelations about the US military mistakenly planning drone attacks that end up only blowing up civilians and then not following up to investigate these failures? Trump's hidden debt and misleading tax filing? On the ground people in Ukraine, Syria, Afghanistan? Various smaller reports on scams in healthcare or housing in the US? In particular with the various tax related investigations, I remember feeling bad for whoever worked on them, because they got released when he was causing immense umbrage with his debate performance and the senate was approving the last justice, so no one paid attention. They are certainly diversifying with more podcasts and video series, some of them more magazine-like or opinion based, but their investigative journalism seems pretty solid.
