U.S. Attorney General Eric Holder is scheduled to speak at a memorial service for the six Sikh worshippers killed in a mass shooting over the weekend.
The U.S Department of Justice said Holder will deliver remarks at the memorial service Friday morning in the Milwaukee suburb of Oak Creek.
The five men and one woman died Sunday when a white supremacist opened fire at the Sikh Temple of Wisconsin. Three other people were injured, including one of the police officers who responded.
The FBI said the gunman shot himself in the head after he was wounded in a shootout with police.
The gunman's motive isn't clear, but FBI officials said they're investigating the case as an act of domestic terrorism.
Meanwhile, Minnesota Gov. Mark Dayton is ordering flags lowered at state and federal buildings to honor victims of the Wisconsin Sikh temple shooting.
Dayton's proclamation orders all flags lowered to half-staff from sunrise to sunset Friday.
The proclamation said "a terrible act of violence was committed against innocent men and women," and the victims and their families deserve "our honor, respect and remembrance."
