white house secretary, eric shinse shinseki, resigned under pressure friday morning. this va story has been building for months, so after the shinseki step aid side, i went down to the eighth floor of the cnn bureau in d.c. and found cnn correspondent, drew griffin. it was his reporting about va health care delays that forced this issue onto the national news agenda. >> i wanted to start by asking when you started looking into the va health care delays, 'cause this is not something that started a month or two ago. >> no, it was last fall, brian, early last fall, and we put our first story on the air in november when we were actually identifying and talking about patients who had died waiting for care. there were actual dead veterans because they got delays in care, basically colonoscopies down in south carolina and georgia. that was our first story. and that was our first attempt to reach general shinseki and ask him if he knew about this and what was being done about it. that was a long time ago. basically, they have tried to shut down our reporting by refusing to talk to us.
