Hill may not have known about the nefarious activities with the underage prostitutes or other allegations. I think she was lazy and spent most of her time at dinners, receptions, and parties drinking, and sleeping the rest of the time.
Gutman was brought back to D.C. to explain himself. Hillary knew.
Whether she did or did not know, she is head of State and it is her responsibility to manage her dept in an honorable, upstanding manner.
Her standing orders should have been that anything like this should be/ will be brought to her attention.
No excuses.....none.
