The owner of 8chan is being summoned to testify before Congress over its link to mass shootings,...

The owner of 8chan, the online message board that's been repeatedly linked to mass shootings, was summoned to appear before the House Committee on Homeland Security, but even the Representatives who made the request on Tuesday seem wary that he'll show.

That's because little is known about Jim Watkins, 8chan's owner, including — it appears — his physical mailing address.

"Please provide the Committee with current physical contact information for you or your authorized representative in the United States so that you can receive communication from the Committee," the House letter read.
