The FBI is investigating a data breach affecting members and staff of the United States House of Representatives after their account and sensitive personal information was stolen from DC Health Link’s servers.

DC Health Link is the organization that administers the health care plans of US House members, their staff, and their families.

Affected individuals were notified of the breach today in an email from Catherine L. Szpindor, Executive Director of the United States House, as first reported by daily call.

“The DC Health Link suffered a major data breach yesterday, potentially exposing the personally identifiable information (PII) of thousands of enrollees. As a member or employee eligible for health insurance through the DC Health Link, your data may understood,” Szpindor said.

“Currently, I do not know the size and scope of the breach, but I have been informed by the Federal Bureau of Investigation (FBI) that the account information and the pit of hundreds of Mernber and House personnel were stolen.

“It is important to note that at this time it does not appear that any MPs or the House of Representatives were the specific target of the attack.”
