A National Science Foundation employee used government credit cards to buy $94,000 worth of computers and tablets, music, cellphones and other personal purchases, according to the Department of Justice.

James Troy Clark, 51, of Fredericksburg, Va., an NSF information technology specialist, was supposed to buy IT supplies for his office.

Instead, he paid personal cellphone bills, spent thousands of dollars on music and movies on the iTunes store, and bought laptops, tablets and other electronic equipment for himself and others between 2010 through July 2013.

He pleaded guilty in federal court last week. His case was investigated by NSF's Office of the Inspector General, which did not release a public report.

Clark faces up to 10 years in prison, according to the DOJ, and is scheduled to be sentenced next month.
