McQueary on sex abuse: "I made sure it stopped"

(CBS/AP) Pennsylvania Gov. Tom Corbett on Sunday said Mike McQueary, the Penn State football coach who said he saw Jerry Sandusky molest a child in 2002, did not meet "a moral obligation"to intervene.

McQueary, who has so far remained silent since the scandal broke, has fired back at criticism that he didn't do enough to stop the alleged assault.

In an email to former teammates, obtained by NBC News, McQueary said: "The truth is not out there fully" and that he "didn't just turn and run" after seeing the alleged molestation.

"I made sure it stopped. I did the right thing ... you guys know me," he wrote, adding that he "had to make quick, tough decisions."

McQueary, a former Nittany Lions quarterback who is now the wide receivers coach, is currently on administrative leave while Penn State decides his job status.

McQueary told a grand jury that in 2002 when he was a graduate assistant, he saw Sandusky sodomizing a boy about 10 years old in a shower at the Nittany Lions' practice center. He said he told his father what happened and then told head coach Joe Paterno, who reported it to his superiors. But those school officials, athletic director Tim Curley and school vice president Gary Schultz, face perjury charges, accused of covering up McQueary's 2002 report.

Speaking Monday night on NBC News' "Rock Center," Sandusky denied allegations he sexually abused eight boys, though he acknowledged he "horsed around" in campus showers - including the alleged incident witnessed by McQueary.

"We were showering and horsing around, and he actually turned all the showers on and was actually sliding across the floor, and we were, as I recall, possibly like snapping a towel - horseplay," he said.
