Alexandria's Republican leader said yesterday that Mayor James P. Moran Jr. may have violated Virginia conflict-of-interest laws when he accepted $10,000 from a local developer, charging that the money was not a campaign contribution but a gift to "Jim Moran's personal slush fund."

Alexandria GOP Chairman W. Michael Holm is asking city Commonwealth's Attorney John E. Kloch to investigate Moran, a Democratic candidate for Congress, saying "there is ample evidence" that Moran personally benefited from the $10,000 and that he cast votes favorable to the developer, Hubert Hoffman.

In January, Hoffman donated $10,000 to a state-chartered political action committee called the Del Ray Democratic Club, which Moran controls. Moran refunded the contribution this week after inquiries by The Washington Post.

When Hoffman made the contribution, the City Council was considering downzoning property Hoffman owns in the Eisenhower Valley. Moran voted in June to allow more development on the property than the council eventually approved. But Moran also opposed a separate Hoffman plan for a massive office building on the site.

Moran has said the Del Ray Democratic Club, named after an Alexandria neighborhood, was intended to support his activities as mayor. He has used money from the fund to pay for such items as tuxedo rentals, Christmas cards and a doctor bill. Hoffman said he gave the money because "I didn't think Jim was too financially solvent."

The contribution, Holm alleged, was intended for Moran's personal, not political, use. Because of the rezoning votes Moran cast, Holm said, "this seriously calls into question whether the state conflict-of-interest statute has been violated."

Moran called Holm's request "nonsense," saying the rezoning proposals he supported called for "substantially less {development} than what Mr. Hoffman recommended."
