The mother of Trayvon Martin is slated to speak in Philadelphia this weekend at the National Urban League's yearly civil rights conference.
U.S. Attorney General Eric Holder is also scheduled to speak at the event, which will also focus on voting rights and job creation.
Holder will speak Thursday about the Supreme Court's striking down of a provision of the Voting Rights Act. Sybrina Fulton, Martin's mother, is scheduled to speak Friday on supporting the attorney general's decision to investigate whether George Zimmerman, her son's killer, could be charged under federal civil rights laws. Zimmerman was acquitted by a jury.
The four-day conference begins Wednesday; however an unofficial kickoff starts tonight at the National Constitution Center. The Urban League of Philadelphia will unveil an original copy of the Emancipation Proclamation, signed by President Abraham Lincoln.
