 After talking to Kislyak, Flynn informed McFarland of the contents of the conversation, who in turn passed on the information to one of her colleagues.In response to these revelations, Senate Foreign Relations Committee ranking members Mark Warner and Dianne Feinstein suggested that she testify before Congress, Cory Booker questioned whether McFarland had been fully forthcoming in her previous testimony, and Committee Chair Bob Corker pronounced her nomination "frozen".By December 5, committee Democrats had placed a formal Senate hold on her nomination.
