Who is Yolanda Cole from Deception Point and what is their importance?

Yolanda is a content editor for ABC studios and is a friend of Gabrielle's. It is she that convinces Gabrielle not to go public with the information about the affair when Tench tells her to, and later it is Yolanda that again convinces Gabrielle that Sexton may be taking illegal campaign funds. Yolanda's press pass allows Gabrielle to get to Sexton's press conference and swap his media kits.
