Looks like Maura Tierney

Perhaps the eyes are similar.. but no, not really. =/

Just saw her on scandal, & had to check here to see if it was here, or her sister. Not only do they look alike, but I think they sound alike.

Thank you! lol If you look at Maura Tierney's pictures from when she had similar long, blonde hair - I think the similarity is quite striking.

They are very lookalike. There's also a ER scene where they appear together:
