Rick Rieder, a senior executive at BlackRock, is a leading candidate for the Federal Reserve chairmanship. However, his history of political donations to Trump's rivals and prominent Democrats may complicate his nomination by Trump, who values loyalty. Data from Polymarket indicates a 32% probability of Rieder's nomination. Federal Election Commission records reveal Rieder's cross-partisan donations, including support for Democrats Pete Buttigieg and Cory Booker in 2020, and Republican Jeb Bush in 2016. Notably, Rieder has not financially supported Trump in the 2016, 2020, or 2024 elections. His contributions have also gone to Democratic leaders like Chuck Schumer and Republican figures such as Mitt Romney. Rieder's largest recent donation was $15,825 to a group backing Nikki Haley in December 2023. Both Rieder and BlackRock have declined to comment on the matter.
