According to ABC News: "Jeffrey Epstein, a wealthy financier charged with sex trafficking, has been a prolific donor to various Democratic campaigns and party committees over the past couple decades, including contributions to some who are now calling for the resignation of a Trump cabinet member who cut a deal for Epstein in a similar case more than a decade earlier.
One of the biggest beneficiaries of Epstein's contributions was then-Senate hopeful Hillary Clinton, who received $20,000 from him in 1999 through her joint fundraising committee with the Democratic Party, according to Federal Election Commission filings. Bill Clinton's presidential campaign also received $1,000 from Epstein in 1992."
And that's just one source of many sources that are available.
