Bear with me, this is a bit convoluted.
Blackrock's biggest shareholder is PNC Financial Services. In 2005 PNC bought Riggs Bank after reports written by Glen Simpson (of Fusion GPS?) had reported on Rigg Bank's apparent CIA connections. For decades Riggs Bank had been popular with VIPs, Presidents, Embassies and the like.
Riggs Bank was used by Saudi Prince Bandar to transfer money to two of the 9/11 attackers. Riggs Bank was also used by Prince Bandar to receive bribes from BAE in what is known as the Al Yamamah arms deal. Baron Bell of Bell Pottinger PR company represented the Saudis and successfully lobbied the UK government to stop investigating the BAE bribery scandal. From 2007 to 2011 Bell Pottinger were paid over half a billion dollars by the US National Security Council, CIA and Pentagon to produce PR material including fake news and fake terrorist videos.
