WASHINGTON (AP) — A top official at the Veterans Health Administration says he's sorry that VA employees have suffered retaliation after reporting alleged wrongdoing.

James Tuchschmidt was one VA official testifying Tuesday night at a hearing before the House Veterans Affairs Committee.

Special Counsel Carolyn Lerner says her office has blocked several disciplinary actions against VA employees who reported wrongdoing.
