WASHINGTON, D.C. (AP)-- A U.S. Senate subcommittee that's investigating the General Motors ignition switch recalls says it will hold a second hearing on July 17.
The Commerce Committee's Consumer Protection and Product Safety Subcommittee likely will summon GM CEO Mary Barra for a return appearance.
Former U.S. Attorney Anton Valukas, who investigated the problem for GM, also is a likely to appear.
A subcommittee spokesman says the witness list hasn't been finalized.
GM spokesman Greg Martin says Barra looks forward to updating the committee on changes that make the company more safety-centered.
GM has recalled 2.6 million older small cars to fix faulty ignition switches. The problem is responsible for more than 13 deaths.
