McCarthy is number two man in the House of Representatives leadership.
..which has nothing specifically to do with the Benghazi Investigation, and he does not speak for this investigation. McCarthy's opinion on this means as little as yours does.
Aside from WHY this investigation is on going, Hillary has repeatedly lied to and deceived the investigating committee (PROVEN - Obstruction of Justice at the least). She is up to her arse in criminal activity, more than what it took to convict Patraeus, and is doing whatever she can to avoid Prison.
McaCarthy is also an IDIOT, making such statements in the middle of an on-going investigation! If I was Gowdy, I punch him in the d@mn nose for publicly undermining my investigation! This just proves McCarthy is as much an ignorant moron as Boehner and McConnell.
