I wouldn't attribute it to just the Clinton's because the CF is larger than them, but there is definitely a lot of suspicious deaths revolving the foundation and people who look into it or pose a threat to it
One of the founding members of the CF and long time friend and associate to the Clinton's is now a convicted *********, there is a concerning number of links between CF and people/companies involved with trafficking/pedophilia, so it's easy to understand why it's so believable that the CF is really as bad as these "conspiracy theorists" think
