Updated| Online hacking group Anonymous has denied responsibility for the recent publication of a list that claims some U.S. politicians belong to the Ku Klux Klan.
Last week, Anonymous said it would soon release the identities of about 1,000 members of the white supremacist organization. Anonymous is expected to release the details on Thursday, the day of the global protest movement known as the Million Mask March, in which demonstrators around the world will march in a protest against corrupt governments and corporations.
Anonymous denies it has any connection to the list of names, which was published Saturday on the website Pastebin. Most of the politicians included on the list—four Republican senators, four Democratic mayors and a Republican mayor—have denied the claims.
