Story highlights A Condoleezza Rice aide says she doesn't remember Colin Powell telling Hillary Clinton to use a private email account

Rice is the second former Secretary of State to cast doubt on Clinton's email defense

(CNN) Another former Secretary of State -- Condoleezza Rice -- has been drawn into the fray over who advised Hillary Clinton to use a private email server while she was America's top diplomat.

An aide to Rice told CNN that Rice has "no recollection" of a conversation between Hillary Clinton and Colin Powell that reportedly took place at a 2009 dinner party of former Secretaries of State, during which Powell allegedly recommended that Clinton use a private email account. The Daily Caller was first to report that Rice had commented on the issue.

Georgia Godfrey, Rice's chief of Staff at Stanford University where she teaches, also told the conservative news outlet that "Dr. Rice isn't doing any media right now. I can tell you, though, that she has no recollection of that conversation either."
