“The subpoena itself is very broad,” said Jeffrey Allen of Allen & Wohrle in Santa Monica, Calif. The committee demanded all documents relating to safety and defects in litigation, he said.

A staff member from the office of U.S. Representative Darrell Issa, R-Calif., the ranking Republican member of the House Committee on Oversight and Government Reform, notified him of the impending subpoena this week, Allen said. The panel has been investigating Toyota’s recall of 10 million vehicles because they are subject to out-of-control acceleration and other problems.
