James Clay Whitson, 45, of Nottingham, Md., was also ordered to pay restitution when he was sentenced Monday, WTOP.com reported.
Federal prosecutors said Whitson and Robert Caleb McCray, 44, conspired to steal almost $1 million from the federal government. Whitson, who worked for the Archives in Silver Spring, Md., would arrange for McCray to be paid at an inflated rate for work that was done at a much lower cost, and the pair would split the proceeds, The Washington Post reported.
In one case, McCray received $50,000 for cleaning fabric panels. He hired a company to do the actual work at a cost of $1,627.
McCray pleaded guilty and also received a 15-month sentence.
