(Columbia, SC) -- In honor of Martin Luther King, we should all be agents of change. That's what New Jersey Senator Cory Booker said yesterday at an MLK Day event in Columbia.
The Democrat was joined by Vermont Senator Bernie Sanders, who are both thought to be White House contenders in 2020.
Sanders, who marched with King in Washington in 1963, told the crowd that many of the things he marched for back then are still things we need to fight for today.
