President Obama to those concerned with the authenticity of his birth in his morning White House Press Briefing stated the following:

 27 April 2011

“…I am speaking for the vast majority of the American people as well as for the press. We do not have time for this kind of silliness. We have better stuff to do. I have got better stuff to do. We have got big problems to solve.” “We are not going to be able to do it if we are distracted, we are not going to be able to do it if we spend time vilifying each other … if we just make stuff up and pretend that facts are not facts, we are not going to be able to solve our problems if we get distracted by side shows and carnival barkers,” the president declared earlier. 

Dr. King to those clergy who criticized his leadership in the Letter from a Birmingham Jail, said:

16 April 1963

While confined here in the Birmingham city jail, I came across your recent statement calling my present activities “unwise and untimely.” Seldom do I pause to answer criticism of my work and ideas. If I sought to answer all the criticisms that cross my desk, my secretaries would have little time for anything other than such correspondence in the course of the day, and I would have no time for constructive work. But since I feel that you are men of genuine good will and that your criticisms are sincerely set forth, I want to try to answer your statement in what I hope will be patient and reasonable terms.

Dr. King once stated

“We are now faced with the fact, my friends, that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history, there is such a thing as being too late. Procrastination is still the thief of time. Life often leaves us standing bare, naked, and dejected with a lost opportunity. The tide in the affairs of men does not remain at flood — it ebbs. We may cry out desperately for time to pause in her passage, but time is adamant to every plea and rushes on. Over the bleached bones and jumbled residues of numerous civilizations are written the pathetic words, “Too late.”
