My source says that is the current one. AP is a past issue, and there is a second one, but I couldn't get info about her. But the third one is an ongoing one, and that is the finance staffer. From what this source said. And let me assure you that this source would have heard it where he/she told me he/she heard it, and it is impressive. This source has no reason to make this up.
You also said that this is no youngster, as in "intern" referred to by Wesley Clark..

"young" is a relative term. Staffers can be anywhere from Mid-20's on up.

This lady may still only be in her late 20's -early 30's, still a looker and a catch for 60 yr old lecher

That's right. I am making that assumption. The source did not indicate the age. The source is not an intern-aged person, but in thirties or so, I believe. I think a staffer on a senate committee would be older than an intern. I would bet she's going to turn out to be in her late 20's early 30's, rather than in her early 20's.
