Bash: I did speak, have to tell you, I did speak to one source close to senator Reid that claims to also know who the Bain investor is that Sen. Reid spoke with, insists it is a credible person and this person if we knew the name we would understand they would have the authority and ability to know about Romney's tax returns. Whether we'll find it out ever, who knows.

DANA BASH, CNN SENIOR CONGRESSIONAL CORRESPONDENT: That's right. We now have a couple of responses, Anderson. Let me read you the first one, that is, "Senator Reid stands by his comments. Governor Romney's continued refusal to release his tax returns raises legitimate questions about what he is hiding and whether he paid any taxes at all. Governor Romney can easily end this debate by following the precedent set by his father and releasing his tax returns."

And as you were coming on the air, Anderson, I got a follow-up like the statement, which also stands by what they call his credible source that Romney has not paid taxes for 10 years, and he's calling Romney playing tricks, many tricks at his disposal for avoiding taxes. So not backing down at all.

But I did speak, I just have to tell you, that I did speak to one source who's very close to Senator Reid who claims to also know who this Bain investor is that Reid spoke with, and insists that this is a credible person and this person if we knew the name we would understand that they would have the authority and the ability to know about Romney's tax returns. Whether we'll find it out ever, who knows. But they're doing this on purpose so that this is the discussion.
