News from 2018? https://www.history.com/news/nikola-tesla-files-declassified-fbi After years of fielding questions about possible cover-ups, the FBI finally declassified some 250 pages of Tesla-related documents under the Freedom of Information Act in 2016. The bureau followed up with two additional releases, the latest in March 2018. In 1952, after a U.S. court declared Kosanovic the rightful heir to his uncle’s estate, Tesla’s files and other materials were sent to Belgrade, Serbia, where they now reside in the Nikola Tesla Museum there. But while the FBI originally recorded some 80 trunks among Tesla’s effects, only 60 arrived in Belgrade, Seifer says. “Maybe they packed the 80 into 60, but there is the possibility that…the government did keep the missing trunks.” https://vault.fbi.gov/nikola-tesla This is a heavily redacted drop of water in a pond. It is around 350 mostly blacked out pages out of 80 trunks full of files. I will read them, but I doubt I will see anything worth noting.

All of the files that were declassified pertain to attempts to gain access to Tesla's research and tracking speculations about what his research contained. None of the files contain any insight to Tesla's actual research and it remains classified.
