Sens. Chuck Grassley and Ron Johnson sent a letter to Department of Veterans Affairs Secretary Robert McDonald Tuesday requesting a whistleblower at the Phoenix, Ariz., VA hospital be transferred to another facility given the harsh treatment he has received since exposing misconduct at the facility.

Brandon Coleman, an addiction therapist at the Phoenix VA hospital, was placed on administrative leave from the facility in February of last year after raising alarms about the VA’s failure to address the needs of suicidal veterans. Coleman also told the Office of Special Counsel and, later, a local media outlet that VA officials had improperly accessed his own medical records.
