WASHINGTON AP – An 88-year-old white supremacist has been charged with murder for killing the security guard who had opened the door to let him into the U.S. Holocaust Memorial and Museum, officials said Thursday.

Security Guard Stephen T. Johns was shot to death Wednesday by Holocaust denier James von Brunn, who had left his car in a lane of traffic outside an entrance to the museum before walking in with a concealed rifle, District Police Chief Cathy Lanier said at a news conference.
