Peiter “Mudge” Zatko, a former Twitter security executive, testified on privacy and security issues relating to the social media company before the Senate Judiciary Committee.
His testimony came amid a whistleblower complaint that he published in August.
Mr. Zatko spoke at length about how Twitter executives have neglected to take steps to protect users' data, which are accessible to about half of Twitter employees.
He further explained the national security risks of such vulnerabilities and mentioned examples of foreign agents who were employed at the company.
This is the first part of the hearing
