Organizers of the Millennium March on Washington said yesterday that they have not received any of the revenue promised by the company that produced the festival related to the event. The FBI confirmed that it is investigating allegations that someone might have walked off with the money, which could be about $750,000.

"We did receive allegations that the funds are missing," said FBI spokeswoman Susan Lloyd. "We have opened a preliminary investigation into this allegation. At this point, we have not independently confirmed any of it, including the amount of money or the people involved."

The accusations are the subject of online news articles and recriminations throughout the gay activist community. Organizers of the nonprofit Millennium March, held the last weekend in April, have not ruled out a lawsuit against Millennium Productions, a for-profit organization that agreed to turn over 65 percent of the revenue from the sale of food, souvenirs and tickets to entertainment events during the festival.
