Ulysses S. Grant Quote

I leave comparisons to history, claiming only that I have acted in every instance from a conscientious desire to do what was right, constitutional, within the law, and for the very best interests of the whole people. Failures have been errors of judgment, not of intent.

This has sometimes been paraphrased: "My failures have been errors of judgment, not of intent". - Eighth State of the Union Address (1876)
