An exasperated Hillary Rodham Clinton made Washington history yesterday at a Senate hearing when she spoke with naked honesty about a question she had no inclination to answer.

“What difference, at this point, does it make?” she actually hollered at Sen. Ron Johnson (R-Wis.) when he had the temerity to ask her repeatedly about the immediate causes of the Sept. 11 attack on our mission in Benghazi.

“With all due respect,” Secretary of State Clinton said, using the phrase that indicates the speaker is about to show the opposite of respect, “the fact is we had four dead Americans.” In a breathtaking display of chutzpah and brazen tastelessness, she used their bodies as a shield against criticisms of her and the administration.
