”We work harder than any other company to identify this behavior,” Mr. Zuckerberg said.
A torrent of criticism has been directed toward Facebook’s cryptocurrency effort since it was announced in June. But Mr. Zuckerberg, who is personally fascinated by cryptocurrencies, is committed to the project.
In the past week, Facebook officials have been on a charm offensive with regulators and lawmakers, leading up to the hearing on Wednesday. And Mr. Zuckerberg has taken on a more assertive role in defending the social network in Washington in recent weeks.
Facebook has one of the biggest influence operations in Washington and has fortified its lobbying in response to the increased government scrutiny this year. The company is on track to spend $12.3 million to lobby the federal government in the first nine months of the year, compared with $12.6 million for all of last year, according to public filings.
But the financial industry and tech companies are growing increasingly leery of the cryptocurrency project. Facebook originally brought on 27 partners to join a Libra Association in Switzerland that is supposed to govern the network. But several big-name partners, including PayPal, Mastercard and Visa, have dropped out.
Mr. Zuckerberg described Libra as a democratizing financial system that would benefit mostly poor consumers, as well as the estimated 14 million people in the United States who do not have access to bank accounts and who cannot afford banking fees.
“People pay far too high a cost — and have to wait far too long — to send money home to their families abroad. The current system is failing them,” Mr. Zuckerberg said in the advance version of his testimony. “The financial industry is stagnant and there is no digital financial architecture to support the innovation we need. I believe this problem can be solved, and Libra can help.”
