【Billionaire founder Ken Griffin of Citadel Investment plans to donate $1 million to Trump’s inauguration fund】 According to Golden Finance, Ken Griffin, billionaire founder of Citadel Investment, plans to donate $1 million to the inauguration fund of President-elect Trump, after previously refusing to contribute to Trump's campaign during this year's election. Griffin has made similar donations in the past, including contributions to Trump's 2017 inauguration and Biden's 2021 inauguration. "I’m sure you will see my name listed again as an inauguration donor," he said after attending a Miami-Dade County League of Cities event on Monday.
