Members of the hacker group Anonymous released what they called a list of Ku Klux Klan members and sympathizers on Thursday.

The document, uploaded on Pastebin, contains hundreds of names and aliases. Among them is Frazier Glenn Miller, the white supremacist who killed three people at a Jewish community center in Kansas City.

The release came three days after the group was mistakenly credited with posting a separate list containing the names of several current lawmakers, like Sens. Dan Coats (R-IN), John Cornyn (R-TX), John Hardy Isakson (R-GA), and Thom Tillis (R-NC). None of them were named in the document posted on Thursday.

Similarly, none of the mayors identified in the prior release from a non-Anonymous Twitter account -- Paul Fraim of Norfolk, Virginia; Jim Gray of Lexington, Kentucky; Kent Guinn of Ocala, Florida; Tom Henry of Fort Wayne, Indiana; and Madeline Rogero of Knoxville, Tennessee -- appeared in Thursday's document, which can be seen below.

Update, 5:15 p.m. EST: The #OpKKK Twitter feed connected to Thursday's document stated that several names were taken off the list "for further investigation."

"We would rather have a smaller, accurate list that we are comfortable with," the group stated.
