Students from Howard University came together with others on Saturday to organize the second rally in two weeks for Trayvon Martin.
Martin was an unarmed teenager that was shot and killed by neighborhood watch volunteer George Zimmerman earlier this year in Florida.
Zimmerman claims he acted in self-defense and has not been charged. But nationwide outrage has sparked a federal investigation that could lead to charges.
Howard University students say they want justice for the teen who was carrying a bag of skittles and a can of ice tea when he was shot.
The protestors marched from Meridian Hill Park to Freedom Plaza, over two miles
