U.S. Sens. John McCain and Jeff Flake say congressional committees are investigating allegations that up to 40 Arizona veterans died while awaiting medical appointments.
The two Republican senators from Arizona held a news conference Friday across the street from the Phoenix VA Medical Center.
Last week, the chairman of the House Committee on Veterans Affairs said the panel's investigators concluded as many as 40 Arizona veteran deaths could be related to VA delays in providing them medical care.
Some veterans say wait times now average 55 days.
Flake says the Inspector General for the Department of Veterans Affairs also is investigating the complaints about Arizona VA facilities.
Phoenix VA Health Care System officials say they've asked for an external review by the Inspector General and will address any problems quickly.
