LOL, they are worried what other dirt they have on Biden.
Its NOT Biden or his crack head son they care about, trust me Dems would throw Biden overboard in a heartbeat if they wanted to..this is ALL about protecting OBAMA, he is their messiah, and they know this ALL leads to Obama, they have to protect him
She's worried about something, for sure.
Legacy? Since this will be shown to be a "show trial" following three years of hysteria and false accusations about nothing, maybe she wants to be remembered as less of a hyperventilating left-wing Jacobin than she (or her party) really is.
That said, I've never seen much of a true display of conscience or love of Country displayed my Mrs. Feinstein; and I do not trust her, or her gesture.
