The Senate Judiciary Committee will hold a hearing featuring testimony from Twitter whistle-blower Peiter “Mudge” Zatko on Sept. 13, the panel’s leaders announced on Wednesday.

The committee said it had subpoenaed Zatko, the company’s former security chief, to appear a day after he went public with allegations that Twitter has failed to adequately protect data on its hundreds of millions of users, leaving their personal information open to hackers and spies.
