The coronavirus pandemic dealt a financial blow to the Clinton Foundation, which saw its donations fall by nearly 75% from the organization’s height when former Secretary of State Hillary Clinton was running for president, according to a report.

In a tax filing reported by Axios, the nonprofit organization founded by former President Bill Clinton said it received about $16.3 million in contributions during 2020. In the previous year, the organization reported $29.6 million in contributions, down from a peak of $62.9 million in 2016, when Hillary Clinton was the Democratic presidential nominee.

Addressing the financial difficulties, foundation CEO Kevin Thurm said last year “was a difficult year for philanthropy” in a letter accompanying its annual financial disclosure. “Across the sector, resources were stretched thinly and fundraising activities were impacted.”
