Clinton server technicians rebuff questions from U.S. Congress

NEW YORK (Reuters) - Two computer technicians declined to answer questions from U.S. lawmakers on Tuesday about the unauthorized private email system that Democratic presidential nominee Hillary Clinton used during her tenure as U.S. secretary of state.

Paul Combetta and Bill Thornton repeatedly invoked their constitutional right not to incriminate themselves during about 10 minutes of questioning while under oath before the House Oversight and Government Reform Committee. A third technician, Bryan Pagliano, declined even to appear, despite a subpoena ordering his testimony.
