Facebook Inc. is negotiating with a key congressional committee for Chief Operating Officer Sheryl Sandberg to testify as soon as next month, people familiar with the talks said, amid questions about the social media giant’s market power and its plans for a digital cryptocurrency called Libra.
Sandberg is expected to appear at a hearing as soon as late October, but officials are still negotiating the details with the House Financial Services Committee, the people said. It’s possible the hearing could slip to later in the year, one of the people said.
