A Twitter whistleblower will testify tomorrow before a Senate panel.
Peiter Zatko will answer questions from members of the Judiciary Committee.
Twitter's former security chief claimed the social media company has major security shortcomings that threaten privacy on the platform and national security. He argued Twitter has made false claims about its security setup, violating a settlement with the FTC.
Zatko also says the company's leadership misled both the government and its own board about the security problems.
