Arianna Grey, an old friend of Ellie Bartlet's. She resides in London and was meant to be Eleonore's maid of honor in the wedding between her and her groom-to-be. The last time she was in USA, her visa was flagged by the DEA, likely because she had narcotics in her bag. She was therefore declared a security risk and was denied the honor of attending the wedding. (Undecideds)
