GOP interrogators: Do you have anything to disclose about the fusionGPS dossier and the involvement of the Hillary campaign and the Obama administration, including yourselves?
Answer: Nope!
GOP interrogators: Okay. Thank you for coming in. We appreciate all your help.
GOP invites Comey, Lynch and Yates to testify on FBI bias claims
