About 300 supporters of Trayvon Martin marched down Pennsylvania Avenue to the White House today to show their support for an investigation into the death of the Florida teen.
Many were students and faculty from the School Without Walls, a D.C. magnet high school located on the campus of George Washington University.
The marchers called for justice for Trayvon Martin, who was shot to death in February while walking unarmed through a gated community in Sanford, Florida.
President Obama was not at the White House. He is flying home from his trip to South Korea and will arrive later this evening.
