(Reuters) - Disclosures from a former Twitter Inc executive turned whistleblower show that at least one Chinese agent is working at the company, Senator Chuck Grassley said in his opening remarks during a Senate hearing on Tuesday featuring testimony from the whistleblower.

The testimony of Peiter "Mudge" Zatko, a famed hacker who served as Twitter's head of security until his firing last year, comes as Twitter and Musk head to trial next month over whether the $44 billion deal should be completed.
