Rep. John Lewis, D-Ga., the youngest and last surviving speaker at the 1963 March on Washington, appeared on CBS News’ “Face the Nation” Sunday to reflect on the legacy left by the civil rights march, where Dr. Martin Luther King Jr. made his famous “I Have a Dream” speech. 

“At the time, I didn’t realize that this would be one of the great speeches, not just in civil rights, but one of the greatest speeches of all time,” Lewis said. 

Bob Schieffer, host of “Face the Nation,” asked Lewis what still needs to be done to realize King’s dream. 

“We as a nation and as a people must continue to come together and pull our country together and create one nation, one people,” Lewis said. 

Expanding on that remark, he continued, “We have to have comprehensive immigration reform. It doesn’t make sense to have hundreds and thousands and millions of people living in the shadows, living in fear and not passing comprehensive immigration reform and setting these people free to become part of this democracy.” 

"There are too many little children living in fear that they’re going to be deported. That’s not right. That’s not fair. That’s not just,” the congressman added. 

When asked about what King would say if he saw America today, Lewis concluded, “Dr. King would say: ‘My dream is in the process of becoming real.’”
