There's a great quote by Muhammad Ali in the museum - "I shook up the world," he said.
And that is what he did.
So did leaders like Sojourner Truth, Frederick Douglass, Booker T. Washington, Martin Luther King, and so many others.
They shook up the world for the better because they inspired our Nation to march toward justice and freedom for all.
Today, and every day, I pledge to continue that march so that every American
no matter his background, no matter her background - has the chance to climb that great ladder of success.
It was very special to accompany Dr. Ben Carson and his family for the first time seeing the Carson exhibit.
I am proud that soon he will serve in my cabinet as the Secretary of Housing and Urban Development.
HUD has a very, very powerful meaning far beyond housing.
It is about transforming our communities.About bringing back hope.And Ben will do a fantastic job.
That's what I am committed to doing also.
I want every African-American child, family, and worker to have access to great schools, safe communities, and good-paying jobs.
