CHARLOTTE, NC (AP) -- For Robert McCauley, the scandal at Veterans Affairs medical centers has touched a nerve.
The 67-year-old retired sergeant says he's heard complaints from friends about the long wait to see doctors.
So the Cary, North Carolina, veteran listened carefully Tuesday when President Barack Obama addressed the VA's problems at the American Legion National Convention in Charlotte.
The president defended his administration's response to lapses that delayed health care for thousands of former service members.
Afterward, McCauley says he was more optimistic about changing the VA's culture.
Other politicians addressed the legionnaires, including Democratic U.S. Sen. Kay Hagan, who is facing a difficult re-election.
Hagan has sought to distance herself from Obama's policies, but she was at the North Carolina Air National Guard Base to greet the president.
