Senator Hillary Rodham Clinton’s campaign said yesterday that it would give to charity $23,000 it had received from a prominent Democratic donor, and review thousands of dollars more that he had raised, after learning that the authorities in California had a warrant for his arrest stemming from a 1991 fraud case.

The donor, Norman Hsu, has raised hundreds of thousands of dollars for Democratic candidates since 2003, and was slated to be co-host next month for a Clinton gala featuring the entertainer Quincy Jones.

The event would not have been unusual for Mr. Hsu, a businessman from Hong Kong who moves in circles of power and influence, serving on the board of a university in New York and helping to bankroll Democratic campaigns.

But what was not widely known was that Mr. Hsu, who is in the apparel business in New York, has been considered a fugitive since he failed to show up in a San Mateo County courtroom about 15 years ago to be sentenced for his role in a scheme to defraud investors, according to the California attorney general’s office.
