The suicide hotline provided by the Department of Veterans Affairs has been sending callers straight to voicemail. Obviously, this is a huge oversight for an organization that serves a group with such a high suicide rate.

Sen. John McCain, a veteran himself, responded to the reports of this failure with disappointment and anger.

“I am deeply saddened and disappointed by the VA’s findings confirming that veterans’ calls to a VA-run suicide hotline have gone unanswered in recent years,” McCain said in a statement. “The VA’s failure to help our most vulnerable veterans is not only unacceptable, but it is shameful.”

Since the suicide hotline was established in 2007, it has received 2 million phone calls and is credited for saving 50,000 lives. Though this is impressive, it’s tough not to wonder whether it could have saved even more veterans had it not put so many veterans on hold.

McCain sponsored the Clay Hunt Suicide Prevention for American Veterans Act to address these systemic issues, which was signed into law in February 2015.

“Unfortunately, the IG’s report shows that there is much more that work still needs to be done to improve suicide prevention services for veterans and change the VA’s culture so that its leaders get in front of problems rather than constantly reacting to them,” McCain said.
