Rebekah Mercer, whose family foundation was a major Trump donor, stepped down from the American Museum of Natural History when her term expired in December.
For years, the Mercer Family Foundation has bankrolled efforts to question climate science with millions of dollars in donations to groups such as the Heartland Institute, CO2 Coalition and Cato Institute.
The Mercer family, among President Trump’s most powerful donors, in 2016 gave nearly $4 million to groups that challenge the scientific consensus on man-made climate change, tax filings reveal.
