This and the pro-bono stuff on the same day. The left is really hammering Roberts today.
For any story like that, the operative question should be 'who benefits from it'?
It is a bit ridiculous to think that a story like that would have the impact of derailing Roberts' support within the GOP.
OTOH, there have been a number of stories which would serve to make him more 'palatable' to the Dims. This one falls into that category. Gives them hope that he's not a hardcore conservative.
Nevertheless, it is a sideshow. He will sail through the confirmation process. 70+ yeas.
