In 2016, leaked emails of John Podesta, chairman of Hillary Clinton's 2016 presidential campaign were released on WikiLeaks, which sparked so-called "pizzagate conspiracy theory". Those emails are not accessible on WikiLeaks website now. Check the link below for the list of the leaks, where Podesta emails are nowhere to be found:

Though not in searchable form, at least those emails can be downloaded via WikiLeaks file dump:

Raw eml files are stored on the following location:

There is also a .gz file, but I'm not sure it's redundant.

I didn't pay much attention to pizzagate at that time. But after seeing media's concerted effort to bury it, I'm not sure this pizzagate conspiracy is really fake because there are actually a few really strange emails.
