A hacker known as Guccifer, who claims he broke into Hillary Clinton's private e-mail server, pleaded guilty Wednesday, NBC News reported.
Marcel Lehel Lazar, who's Romanian, entered guilty pleas to charges of identity theft and unauthorized access to protected computers before a federal judge in Alexandria, Virginia. He could face up to seven years in prison.
Prosecutors said he broke into the e-mail and social media accounts of about 100 Americans, including members of the family of former presidents George W. and George H.W. Bush.
Lazar served time in a Romanian prison and was brought to the U.S. in late March to face federal charges.
