Russ Choma for Mother Jones:

A liberal watchdog group has filed a complaint with the Federal Election Commission charging that the super-PAC supporting Jeb Bush, Right to Rise, received contributions from companies that were used to shield the identities of the donors. The six-figure donations from these mysterious entities—one of which has ties to an investment firm run by a Bush relative—were first reported byMother Jones.

The complaint, submitted by Citizens for Responsibility and Ethics in Washington (CREW), requests an investigation into Heather Oaks LLC and TH Holdings LLC, which each contributed $100,000 to Right to Rise last winter. As Mother Jonesreported, each of these firms—which are limited liability corporations (LLCs)—appears to have virtually no real-world presence or assets, suggesting they may have been used as a conduit by donors seeking to keep their fingerprints off these contributions. Under current campaign finance laws, it’s legal for a corporation to donate to a super-PAC. But if a corporation or individual makes a donation through a company to hide their identity, that’s a potential violation of campaign finance law.
