Celebrate Martin Luther King Day and all the many wonderful things that he stood for. Honor him for the great man that he was

The Rev. Martin Luther King Jr.’s eldest son brought along his colleagues who are associated with the Drum Major Institute— the non-profit progressive think tank and community action group he’s president of.

After their meeting ended, King III told the media there that they had a “constructive” discussion.

“It is very clear that the system is not working at its maximum” when it comes to the participation of voters, he said, and Trump repetitively stated “that he is going to represent all Americans… I believe that’s his intent. I believe we have to consistently engage with pressure, public pressure. It doesn’t happen automatically, my father and his team understood that, did that.”

King III has called to establish a free government photo identification that could allow Americans who don’t have a driver’s license or other ID to cast votes.

He had even urged the Obama administration to make a photo ID pervasive.

On Monday, Trump tweeted, “Celebrate Martin Luther King Day and all the many wonderful things that he stood for. Honor him for the great man that he was”
