Didn't Graham already admit to sitting on a "moot court" panel with Alito in the well? Having his name on a list won't give any more ammunition, it only confirms what has already been admitted. And Alito testified under oath in these hearings that he was not coached in how to answer. IOW, lots of smoke and fury will be generated - needs to be on order to provide cover for some amount of voting against advise & consent.
Oh...okay...I didn't know that Graham had made it known already..
