The U.S. Capitol Police have announced the arrest of an individual who allegedly posted the private information of U.S. senators on the Internet.

While it has not been officially confirmed, this could be related to the doxing of U.S. Senators Orrin Hatch, Mike Lee, and Lindsey Graham's on their Wikipedia pages last week during Brett Kavanaugh and Christine Blasey Ford hearing. During the hearing, someone modified the senator's pages to include personal information such as their home addresses and phone numbers.

According to the revision history for the senators, the modifications appeared to have been done on September 27th at around 9 PM by someone using the IP address 143.231.249.130. This IP address resolves to the hostname chyron.house.gov, and based on the domain, is affiliated with the U.S. House of Representatives.
