On September 16th, BlackRock is re-hiring Mike Pyle, who was a senior aide to Harris and also served as an executive at the company. In a memo sent to employees on Monday, BlackRock said Pyle had been informally providing economic advice to Harris's presidential campaign, and he would advise investors on geopolitical and economic risks as deputy head of a unit about $3.20 trillion in size, which is part of BlackRock's overall $10.60 trillion business.
