Quote:Three IT specialists involved with Hillary Clinton’s private email server on Tuesday refused to testify before the House Oversight Committee on deletions of some of Clinton’s emails.

One of these three, Bryan Pagliano — the former State Department employee who set up the server — defied a subpoena and failed to appear at the hearing altogether.

The other two, engineers at the outside firm that managed Clinton’s server, appeared under subpoena but invoked their Fifth Amendment rights in response to every question.

Outraged Republicans quickly threatened reprisal against Pagliano, who has long been a flashpoint in various investigations into the server.

The former State technician famously exercised his right not to testify against himself before the House Select Committee on Benghazi in 2015. He was also reportedly awarded an immunity deal during the FBI’s now-closed investigation into Clinton’s use of the server while secretary of State.

“I will consult with counsel and my colleagues to consider a full range of options available to address Mr. Pagliano’s failure to appear,” Chairman Jason Chaffetz (R-Utah) said. “When you are served a subpoena by the United States Congress, that is not optional.”
