>>> MORE THAN 450 CATHOLIC CLERGY ACCUSED OF ASSAULTING 2000 CHILDREN.

>> IT IS MY SINCERE HOPE THAT THIS REPORT WILL SHINE A LIGHT ON THOSE WHO VIOLATED THEIR POSITION AND ABUSED INNOCENT CHILDREN.

AND THOSE IN CHURCH LEADERSHIP , WHO COVERED UP THAT ABUSE.

>> MATT MASTERSON JOINS US NOW.

THE ATTORNEY GENERAL SAYS THIS IS A MULTI-YEAR INVESTIGATION.

WHAT MORE ARE WE LEARNING?

>> THEY FOUND THAT FORTNER HUNDRED AND 50 CATHOLIC CLERICS AND RELIGIOUS BROTHERS HAVE ASSAULTED CHILDREN AMONG ILLINOIS DIOCESES.

THIS GOES BACK DECADES AND OF THAT TOTAL , THEY REPORTED 103 .

>> SO THEY LIED TO THE PUBLIC?

>> YES, THEY LIED.

ROWELL HIMSELF DID NOT GO QUITE THAT FAR BUT POINTED OUT THE DISCREPANCIES AND SAID THAT THE NUMBERS SPEAK FOR THEMSELVES.

>> THE CHICAGO ARCHDIOCESE RELEASED A VIDEO TODAY.

>> SOME OF THE WAR THE CALLERS VIOLATED THEIR VOWS , ABUSING GOD'S LITTLE ONES.

THIS IS PAINFUL FOR ME AND MY BROTHERS.

>> WHAT DID THEY SAY ABOUT THIS DISCREPANCY?

>> HE NOTED THAT THIS WAS FAR GREATER THAN THEIR OWN LIST AND I WILL NEVER EXPLAINED TO THEM HOW THESE WERE ACTUALLY SUBSTANTIATED.

>> YOU ALSO SPOKE WITH THE HEAD OF THE SNAP CHAPTER .

WHAT DID THEY HAVE TO SAY?

HE HIMSELF IS THE SURVIVOR OF ABUSE AT THE HANDS OF A PRIEST AND HE SAID THAT UNFORTUNATELY, THIS IS A MASSIVE UNDERCOUNT.

THEY ARE URGING OTHER STATES TO RELEASE REPORTS OF THEIR OWN FOR TRANSPARENCY AND DOES NOT BELIEVE THAT THERE WILL BE MASSIVE CHANGES WITHIN THE CHURCH.
