The headquarters of the U.S. Securities and Exchange Commission (SEC) are seen in Washington, July 6, 2009.
The SEC's Boston regional office has been probing Freedom for months, the report said, citing documents seen by CNBC and people familiar with the matter.
The allegations in the Hindenburg report are without merit, Freedom had said then.
The U.S. Attorney's Office for Massachusetts is also making preliminary inquiries into Freedom, the CNBC report added.
The SEC declined to comment on the existence or nonexistence of a possible investigation, whereas the Department of Justice and Freedom did not immediately respond to Reuters requests for comment.
