I suspect the “evidence” (which way BTW-”for” or “against” the Cardinal) you demand is probably not available outside the confessional...but if you’re truly interested you could start with Matt Abbott’s discussion about the circle the good padre ran with and the various facts and allegations therein...none of which are particularly clerical
There could never be any evidence for the Cardinal, because evidence for something that never happened, or don't exist, ect... can not possibly exist. Otherwise, it is an explicit sin against your neighbor to fling filthy allegations and then claim the "evidence" is hidden, or was somehow lost. ie. "the dog ate my evidence, then he died".

Ah ha! Guilt by association. Selective association at that, because "the good padre" was the head and leader of the USCCB, a member appointed by and in good standing amongst the Magisterium and the Pope. That don't matter with Mr. Abbott though, since Mr. Abbott's will was not honored, YOPIOS notwithstanding. All that matters with Mr. Abbott and whats his name et al, is that Cardinal Bernardin is defamed in the most heinous way.
