* Harvey Weinstein was covered up by many in the media as detailed in Ronan Farrow's Pulitzer Prize winning piece in The New Yorker [1]
* ABC killed a story about Jeffery Epstein in 2015 in part to retain access to the royal family. Epstein continued to sex traffic children for 3 years after this report would have aired [2]
* The BBC covered up for Jimmy Savile's pedophila (and other horrors I won't reprint here) for decades. The head of the BBC during that time left right before the scandal came to light to become the current CEO of The New York Times [3]
There are many other examples but these are recent and well documented.
