Sens. John McCain and Jeff Flake are calling for a Senate investigation and hearings into allegations that up to 40 Arizona veterans died while awaiting medical appointments at the Phoenix VA Medical Center.
The two Republican senators from Arizona sent a letter Wednesday to leaders of the Senate Committee on Veterans' Affairs requesting a probe into "recent reports of gross mismanagement and neglect" at the facility.
