Here is more from the Washington Post:
In 2019, anonymous donors gave the think tank Capital Research Center, or CRC, $596,000 that was designated for Crowdsourcers, according to tax filings and audits the think tank submitted to state regulators. The majority of that money, $400,000, was routed through yet another nonprofit, Donors Trust, according to that organization’s tax filings.
CRC, which bills itself as an “investigative think tank,” is dedicated to uncovering anonymously funded influence campaigns by unions, environmental groups and other left-leaning nonprofits. Among its trustees is Edwin Meese III, the conservative elder statesman and former attorney general in the Reagan administration. Its president is Scott Walter, a former aide to President George W. Bush.
CRC was founded in 1984 by Willa Johnson, a former senior vice president at the Heritage Foundation.
