The legal clash between Twitter and former legal chief Vijaya Gadde is heating up, with the  company’s lawyers blasting her request to be reimbursed $1.1 million for legal fees she rung up preparing to testify before a U.S. House committee as “unreasonable in the extreme.”

Gadde and two other former Twitter executives sued the San Francisco-based company in the Delaware Court of Chancery in April seeking reimbursement for legal fees they’d racked up on Twitter-related matters, including lawsuits and investigations, since Elon Musk completed his $44 billion purchase of the company in October and immediately fired them.
