Democratic fund-raiser Johnny Chung has agreed to help federal prosecutors look for campaign-finance abuses, even shaking hands with them before he was arraigned on charges of illegally contributing thousands of dollars.

The Taiwanese-born businessman will plead guilty next week to charges that include funneling $20,000 in illegal contributions to the Clinton-Gore re-election campaign and $8,000 to the campaign of Sen. John Kerry, D-Mass, Chung's attorney, Brian Sun, said Monday.Chung, 43, actually contributed more than $400,000 to Democratic causes and candidates between 1994 and 1996. The reduced numbers are the result of the plea bargain.

Chung is the first major figure in the campaign finance scandal to offer cooperation. He could face 37 years in prison and $1.45 million in fines. But in such plea agreements, the sentence usually is contingent on how much information is provided and whether it is found to be useful.

Sun would not detail what information Chung has provided.
