Sen. McCain: If VA hospitals cooked books on wait times, people should go to jail

(CNN) – Clerks scheduling medical appointments for veterans were "cooking the books" at their bosses' behest to hide the fact some had to wait weeks, if not months, for appointments, a VA scheduler in San Antonio said Thursday.

The Office of Inspector General confirms to CNN that it has staff investigators on the ground in San Antonio looking into the allegations.

The allegations surrounding this Texas VA hospital comes as the federal department fends off claims of potentially deadly delays at other facilities, including claims of a secret wait list in Phoenix that was first reported by CNN.

"If it is what it appears to be, this isn't just resignations, this is violations of the law, people should go to jail," says Sen. John McCain, R-Arizona.

"Not surprisingly ... this is spreading to Colorado, to Texas, to California, to Atlana, and it's really terrible, and we need to hold people accountable," says McCain.
