Twitter Investors Back Musk’s Takeover Bid After Whistleblower Testifies in Congress

WASHINGTON—Twitter shareholders approved the $44 billion takeover that Elon Musk is trying to abandon on the same day that a whistleblower alleged at a hearing on Capitol Hill that the social-media company misled regulators about security failures.

Former Twitter security executive Peiter Zatko, who was fired by the company in January, told the Senate Judiciary Committee on Tuesday that Twitter executives’ “incentives led them to prioritize profits over security,” echoing his whistleblower complaint.
