The President is merely the most important among a large number
of public servants. He should be supported or opposed exactly to
the degree which is warranted by his good conduct or bad conduct,
his efficiency or inefficiency in rendering loyal, able, and
disinterested service to the nation as a whole. Therefore it is
absolutely necessary that there should be full liberty to tell
the truth about his acts, and this means that it is exactly as
necessary to blame him when he does wrong as to praise him when
he does right. Any other attitude in an American citizen is both
base and servile. To announce that there must be no criticism of
the President, or that we are to stand by the President, right or
wrong, is not only unpatriotic and servile, but is morally
treasonable to the American public. Nothing but the truth should
be spoken about him or any one else. But it is even more
important to tell the truth, pleasant or unpleasant, about him
than about any one else.
— John Fitzgerald Kennedy
