The seven-figure donation, made June 29 to the pro-Clinton Priorities USA Action, came from another super political action committee, called Fair Share Action. Its two lone contributors are Fair Share Inc. and Environment America Inc., according to records filed with Federal Election Commission.
Those two groups are nonprofits that are not legally required to reveal information about their donors. Such contributions are sometimes called “dark money” by advocates for stricter campaign finance rules.
“This appears to be an out-and-out laundering operation designed to keep secret from the public the original source of the funds given to the super PAC, which is required to disclose its contributors,” said Fred Wertheimer, director of one such group, the Washington-based Democracy 21.
While another Democratic competitor, Vermont Sen. Bernie Sanders, has rejected the support of super PACs altogether, Clinton has been plain that she needs big-money help.
