Marcel Lazar, 44, who used the alias online, had pleaded guilty in May to charges including unauthorized access to a protected computer and aggravated identity theft after being extradited from Romania.

Lazar's public defender, Shannon Quill, was not immediately available for comment.

Lazar has said in interviews he breached Clinton's private server at her home in Chappaqua, New York, but law enforcement and national security officials say that claim is meritless.

Lazar is believed to have hacked into email accounts of about 100 victims between 2012 and 2014.
