It is an unusual charity brochure: a 13-page document, complete with pictures of fireworks and a golf course, that invites potential donors to give as much as $500,000 to spend time with Tom DeLay during the Republican convention in New York City next summer — and to have part of the money go to help abused and neglected children.

Representative DeLay, who has both done work for troubled children and drawn criticism for his aggressive political fund-raising in his career in Congress, said through his staff that the entire effort was fundamentally intended to help children. But aides to Mr. DeLay, the House majority leader from Texas, acknowledged that part of the money would go to pay for late-night convention parties, a luxury suite during President Bush's speech at Madison Square Garden and yacht cruises.

And so campaign finance watchdogs say Mr. DeLay's effort can be seen as, above all, a creative maneuver around the recently enacted law meant to limit the ability of federal officials to raise large donations known as soft money.

"They are using the idea of helping children as a blatant cover for financing activities in connection with a convention with huge unlimited, undisclosed, unregulated contributions," said Fred Wertheimer, president of Democracy 21, a Washington group that helped push through the recent overhaul of the campaign finance laws.

Other lawmakers may well follow Mr. DeLay's lead. Already Senator Bill Frist, the majority leader, is planning to hold a concert and a reception in conjunction with the convention as a way of raising money for AIDS charities.
