A Senate hearing reviewing "Stand Your Ground" laws will take place Tuesday after previously being delayed.
The original hearing was postponed in mid-September following the killings at the Navy Yard in Washington.
The hearing Tuesday will take place before the Senate Judiciary Subcommittee on the Constitution, Civil Rights and Human Rights, chaired by Senate Majority Whip Dick Durbin (D-Ill.).
The witness list is not yet public, but Trayvon Martin's mother, Sabrina Fulton, was set to attend the previously scheduled hearing.
"Stand Your Ground" laws, which exist in many states, emerged as a contentious issue after the shooting death of Martin and subsequent not guilty verdict in the trial of George Zimmerman.
