The Negro Detroit congressman said last night he will demand "the right to vote for Southern Negroes, an end to the intimidation of Negro citizens and the creation of a special civil rights division in the Justice Department."

Diggs spoke at a church rally called in support in Montgomery, Ala., Negro leaders under indictment in an alleged bus-boycott conspiracy.

The Rev. Ralph D. Abernathy, one of those indicted, also spoke. He denied the movement against using city buses was a boycott and described it as a "protest against indecency and mistreatment."

"When we go on trial, Montgomery will be on trial, too," he said.
