I think she would have said the names if they were Republicans. I bet they're Southern Democrats.
Probably not even. It would be a "breach" of sorts and other Senators would have a hard time trusting her in the future. I would think the milieu in the Senate is that these kinds of things are handled "in-house".
Keep in mind that the claims would be denied and can't really be substantiated anyways. It would backfire.
Exactly. I'm not saying they were definitely Republicans, but the fact that she didn't say the names doesn't make it any less likely that they are. Gillibrand isn't going to use this as some cheap political tactic either way; she has a message about women in the workplace that she wants to send and is trying to convey that Congress isn't immune from this.

Initially, I couldn't put my finger on why I thought Gillibrand made the right call by not naming the senators who harassed her, but I think Schwartz hit the nail on the head with her two reasons. I think it's still interesting to speculate who the culprits could be, but if Gillibrand wants to keep the identities of the senators to herself, that's just fine.
