Facebook Inc. Chief Executive Officer Mark Zuckerberg will testify before a key congressional committee that deals with the finance industry later this month, the latest sign of rising opposition to the social-media giant’s plans to create a cryptocurrency.

Zuckerberg will appear before the House Financial Services Committee on October 23, according to Maxine Waters, the panel’s Democratic chairwoman. He’ll be the sole witness at the hearing, which is advertised as an examination of Facebook’s broad impact on the financial services and housing industries, Waters said in a Wednesday statement.

Zuckerberg looks forward to testifying before the committee and responding to lawmakers’ questions, a Facebook spokesman said.

The hearing will be second held by Waters in a matter of months that features a Facebook senior manager. In July, both Democratic and Republican members on her panel grilled David Marcus, the executive leading Facebook’s development of the digital token, known as Libra. Lawmakers are concerned that the coin might be used to bypass money-laundering rules or that it could undermine government control over the flow of money.

Facebook announced in June it’s trying to create a new cryptocurrency using similar technology to that of Bitcoin, saying it would lower the cost of payments and money transfers. The company helped form a new organization, called the Libra Association, that’s incorporated in Switzerland and would manage the currency.

Blowback to the plan was swift. Federal Reserve Chairman Jerome Powell has said Libra could pose a risk to the financial system, and its drawn criticism from President Donald Trump and Treasury Secretary Steven Mnuchin. The French and German finance ministers have said they would block the project.
