Tens of thousands of people marched in Washington, D.C. Friday on the 57th anniversary of Martin Luther King Jr.' s "I Have a Dream" speech.

King gave his historic speech Aug. 28, 1963, in the nation's capital at the "March for Freedom and Jobs."

A similar message was embraced at a march and rally at the Lincoln Memorial Friday, decades later.

Martin Luther King III was among the speakers at Friday’s event.

"In so many ways, we stand together today in the symbolic shadow of history, but we are making history together right now," King III said.

Organizers with the National Action Network say on their website, "We are recommitting to the dreams of Martin Luther King Jr. left unaddressed. This is a Commitment March, not a commemoration march, and we are marching for policing and criminal justice reform."

Other speakers included Rev. Al Sharpton and relatives of people killed by police, including the Bridget Floyd, the sister of George Floyd.

"What will be your legacy? Will your future generations remember you for your complacency, your inaction?" Bridget Floyd said.

Among those watching the march from home were Marge and Peter Rogatz, of Port Washington. Now 92 and 94 years old, they were among hundreds of Long Islanders who attended the 1963 march.

“People of different colors, of different ages, a feeling of peaceful forcefulness… We all knew we were seeing history at that moment," Marge Rogatz said.

Marge Rogatz also founded the Roslyn Committee for Civil Rights in 1962 and, more recently, the nonprofit ERASE Racism.

"I think we have made some progress, but we have definitely not made enough progress. We have been, not slow, it's even worse than that. Most people have just had their heads in the sand. They have just not recognized at all what has been going on," Rogatz says.
