Rieder has donated to opponents of Trump and senior Democrats, which may cause obstacles for him in the race for Federal Reserve Chairman.

Records from the Federal Election Commission show that Rick Rieder, a senior executive at BlackRock who is considered a top candidate for the next Chair of the Federal Reserve, has donated to some of President Trump's major political opponents and Democratic Party leaders. This history may test Trump's tendency to favor loyalists in his appointments. According to FEC data matching the name and employer information of Rieder, his donation history is extensive and involves both parties in the United States, including supporting Nikki Haley's presidential campaign in 2024, supporting Democrats Pete Buttigieg and Cory Booker in 2020, and supporting Jeb Bush's candidacy in 2016. FEC records show that Rieder did not support Trump during his campaigns in 2016, 2020, and 2024.
