WASHINGTON (AP) — A federal investigative agency is examining 67 claims of retaliation by supervisors at the Department of Veterans Affairs against employees who filed whistleblower complaints — including 25 complaints filed since June 1, after a growing health care scandal involving long patient waits and falsified records at VA hospitals and clinics became public.

The independent Office of Special Counsel said 30 of the complaints about retaliation have passed the initial review stage and were being further investigated for corrective action and possible discipline against VA supervisors and other executives. The complaints were filed in 28 states at 45 separate facilities, Special Counsel Carolyn Lerner said.
