Chuck Grassley actually said...

"this does not guarantee that you will not be retaliated against, with emphasis upon even though retaliation for making a protected disclosure is illegal"

"That is the only way to say that the culture needs to be changed if the President says it needs to be changed."

"the retaliation at the FBI reflects a culture and that culture needs to be reformed both legally through actions of Congress"

"I have suggested to five Presidents individually and it has never been done and I do not imagine it will ever be done."
