And Holder is investigating her son’s death for possible federal charges against Zimmerman, isn’t he supposed to be impartial?

(AP) — The mother of slain Florida teenager Trayvon Martin and U.S. Attorney General Eric Holder will speak in Philadelphia at the National Urban League’s annual conference, which will focus on civil rights, voting rights and job creation.

The four-day event, which begins Wednesday, comes less than a month after the Supreme Court struck down a key provision of the Voting Rights Act and not long after the man who shot Martin was acquitted in the racially charged case.

The league is one of the nation’s oldest civil rights organizations. The conference, titled “Redeem the Dream: Jobs Rebuild America,” is expected to attract about 6,000 people and also focus on strengthening economic opportunities for African-Americans, CEO Marc Morial said.
