Not happy with Bolton, but didn't expect this. The whole article is worth a read and maybe post by someone who knows how. Apologies if a repeat, not able to keep up lately.
"Another individual tied to Cambridge Analytica was John Bolton, who gave the firm $800,000 in 2016. According to data from Open Secrets, Bolton's Super PAC has received millions from the Mercer-connected Renaissance Technologies since 2014. Bolton has consistently acted to undermine and sabotage Donald Trump's foreign policy agenda since being appointed as National Security Advisor in 2018. Bannon was allegedly one of a number of individuals who recommended Bolton to Trump after he fired Bolton's predecessor HR McMaster."
