In an earlier interview, Freeman said he knew nothing about The Filming. "I suggest you track them down," he said.
Labor Department officials have declined to confirm that the election inquiry is underway, or to say whether they are investigating the union's spending practices.
Another Stern spokesman, Steve Trossman, has said the SEIU had received no allegations of financial irregularities by Freeman until The Times raised questions about the local's finances last month. But a source close to the union has said that Trossman was informed six years ago of some concerns about Freeman's spending habits and his having fathered a child with Planells, who was then a union staffer.
Trossman has said he remembers little about those reports, including whether he had alerted Stern to them.
Freeman has said the golf tournament netted $80,000 to $100,000 for both a charity he founded, the Homecare Workers Training Center, and a second nonprofit he helped launch, The Long-Term Care Housing Corp.
The local's financial reports show that it spent $418,000 on the tournament, or at least $123,000 more than it received in reimbursements -- not counting about $7,000 in unspecified lodging costs at the Four Seasons.
Freeman has said some reimbursements may be outstanding, more than a year after the tournament was held.
Last year, the local paid his wife's company, Lotus Seven Productions, about $178,000, the financial reports show. The firm received roughly $36,000 the year before.
Labor Department officials said that only after The Times raised questions about the payments to Lotus Seven did Freeman file disclosure forms that require union officers to reveal payments to entities in which a spouse has an interest.
Freeman has said Lotus Seven has produced 10 videos that promote the local's work and have been shown on lease-access cable channels. He and his wife have said that she did not personally profit from the payments to her company.
The Homecare Workers Training Center has paid nearly $100,000 a year to a day-care service operated by Planells' mother, Carmen Planells. The training center began itemizing the payments on its Internal Revenue Service reports in 2002, the year after Freeman and Pilar Planells had a daughter together, records show.
Freeman has defended the arrangement with Carmen Planells, saying her firm provides high-quality day care. His wife and brother-in-law, Hernando Planells Jr., are listed on state incorporation papers as officers in the company.
Under the trusteeship, the union's national office will take control of the local's finances and appoint an interim president, said Stern spokeswoman Ringuette, who added that she had no other details.
