An organizer of a white supremacist rally last year in Charlottesville, Va., where one woman died plans to hold a march across the street from the White House on the rally’s anniversary in August, federal officials said on Thursday.

The National Park Service has approved an application for a permit from the organizer, Jason Kessler, for an event on Aug. 11 and 12 that he described as a “white civil rights rally” for 400 people at Lafayette Park in Washington. Mr. Kessler submitted the permit request on May 8 and it was granted the next day, but he has not yet received final approval because the Park Service has asked for additional logistical details about the rally, a spokesman said.

“The process itself is no different from anything else,” Mike Litterst, a spokesman for the National Park Service, said in an interview on Thursday, referring to permit review. “The Park Service is content neutral when it comes to these sort of decisions.”
