The New York Daily News said Wednesday the recording of Clinton, who was a U.S. senator for New York at the time it was created, featured the Democratic politician thanking Hsu for his fundraising help in her presidential bid.
"You are working so hard for me that I just don't know what to say any more," Clinton said in the recording. "I've never seen anybody who has been more loyal and more effective and really just having greater success supporting someone than you."
The recording was made while Hsu was serving as a fundraiser for the Democratic Party. It was used in the Manhattan Federal Court case against Hsu amid allegations he used the recording to show investors his clout among top Democratic Party officials, the Daily News said.
Hsu, 58, is accused of violating federal campaign finance laws. The fundraiser has already pleaded guilty to charges related to his involvement in a $20 million Ponzi scheme, the Daily News said.
