As Clinton calls for campaign finance reform, group backing her gets $1M from anonymous donors

WASHINGTON – Hillary Rodham Clinton told a cheering crowd at her largest rally so far that “the endless flow of secret, unaccountable money” must be stopped.

Two weeks later, the main super political action committee or PAC backing her bid for the Democratic presidential nomination accepted a $1 million contribution that cannot be traced.

The seven-figure donation — made June 29 to the pro-Clinton Priorities USA Action — came from another super political action committee. Its sole donors are nonprofits that are not legally required to reveal information about their contributors.

Such contributions are sometimes called “dark money” by advocates for stricter campaign finance rules.

One group has called on the Clinton super PAC to return the money. But a spokesman says it is “playing by the rules.”
