Former Penn State coach Jerry Sandusky admitted to showering and  horsing around with young boys but said he is not a pedophile in an  exclusive interview with Bob Costas for NBC News' Rock Center airing  tonight at 10 pm/9 CT.  "I say that I am innocent of those charges," said Sandusky in a phone interview with Costas. 
When asked by Costas, "Are you a pedophile," Sandusky responded "No."
Joe  Paterno?s one time defensive coordinator was charged earlier this month  with 40 counts of sexually abusing eight boys. He is currently free on a  $100,000 bond and has denied any wrongdoing. The allegations date back  to 1994, according to a grand jury report. A grand jury report detailed  claims of alleged sexual encounters with young boys in Paterno's home,  hotels and Penn State locker rooms.
"I could say that I have done  some of those things. I have horsed around with kids I have showered  after workouts. I have hugged them and I have touched their legs without  intent of sexual contact," said Sandusky.
When pressed by Costas  about what if anything was Sandusky willing to concede that he'd done  was wrong, Sandusky said, "I shouldn't have showered with those kids."
The  scandal has tarnished the reputation of the once heralded football  program, leading to the departure of coaching legend Paterno and three  other university officials. It?s also left students and residents of  State College, Penn., shocked.
The sight of the 67-year-old  Sandusky in handcuffs is hard to reconcile with his public image of a  devoted father of six adopted kids who founded a charity to help at risk  youth.  That charity, The Second Mile, has also come under fire. 
All  of the alleged sex abuse victims met Sandusky through their  participation in The Second Mile.  Sandusky founded the charity in 1977  as a group foster home for troubled boys.  It spawned into a non-profit  organization that has raised millions of dollars to help young boys and  girls.  Today, Chief Executive Officer Jack Raykovitz?s resignation was  announced by the non-profit organization?s board of directors. Grand  jury testimony alleges that Raykovitz was aware of at least one of the  allegations against Sandusky.
In an NBC News interview from 1987,  Sandusky joked that he started The Second Mile because he was a  ?frustrated playground director.?
?I enjoy being around children. I enjoy their enthusiasm. I just have a good time with them,? Sandusky said.
Sandusky  gave up his day to day duties at the organization in 2010. By that  time, at least two people had allegedly witnessed Sandusky sexually  abusing two different boys in showers on Penn State?s campus, according  to a grand jury report.
While Sandusky retired as a coach at  Pennsylvania State University in 1999, he continued to have access to  Penn State?s facilities.  In 2002, he was banned from bringing minors to  campus athletic facilities after then graduate student Mike McQueary  allegedly witnessed Sandusky molesting a boy, according to the grand  jury report. The incident was never reported to police or investigated  by university police.  Sandusky allegedly violated the order not to  bring minors to campus by bringing at least one victim to the campus  after 2002, according to the grand jury report.
The alleged  victims testified that they were abused in hotel rooms, Sandusky?s own  home and on Penn State?s campus. Some victims testified that Sandusky  would visit them frequently at their schools when they didn?t return his  phone calls, according to the grand jury report.
