From President Calvin Coolidge:

“It is my duty to extend to every individual the constitutional right to the presumption of innocence until proven guilty.”

“I have another duty equally constitutional, and even more important, of securing the enforcement of the law. In that duty I do not intend to fail.”

“I am a Republican, but I can not on that account shield anyone because he is a Republican. I am a Republican, but I can not on that account prosecute anyone because he is a Democrat.”

“It is not for the President to determine criminal guilt or render judgment in civil causes. That is the function of the courts. It is not for him to prejudge. I shall do neither; but when facts are revealed to me that require action for the purpose of insuring the enforcement of either civil or criminal liability, such action will be taken. That is the province of the Executive.”
