An election watchdog organization is asking the Federal Election Commission to investigate a recent $500,000 donation to a super political action committee aiding Marco Rubio from a mystery firm headed by a New York investor.
The complaint Friday by the Citizens for Responsibility and Ethics in Washington seeks an investigation into IGX LLC and the Conservative Solutions PAC for the masked donation.
The donor, Andrew Duncan, of Brooklyn, New York, acknowledged to The Associated Press earlier this month that he had routed his contribution through IGX.
Duncan and a spokesman for the committee did not immediately respond to the AP'S requests for comment.
Efforts by good government groups to stem the use of shadowy corporate entities to channel large political donations have been stymied by the FEC's internal political paralysis.
