This is a quote from Barack Obama’s speech on August 28th, 2013:
If we’re honest with ourselves, we’ll admit that during the course of 50 years there were times that some of us claiming to push for change… lost our way.
He was referring to the 50 years of struggle for equality and civil rights in the USA since the 1963 “March on Washington for Jobs and Freedom”. He proceeded to cite examples of failed change. Indeed many of those promising, advocating, and even wanting change, failed to adequately live up to their promises.
Here is a totally unrelated picture of Mr Obama in the 2008 campaign.
