"Court records show a former government scientist accused of attempted espionage last week pleaded guilty earlier this year to overbilling NASA and the Department of Defense more than $265,000 for contracting work. The January plea by 52-year-old Stewart Nozette of Chevy Chase, Md., was detailed in court records unsealed Friday. The records state the documents were sealed because Nozette was cooperating in unrelated government corruption investigations."

"According to the unsealed court documents, Nozette was charged with defrauding the government and tax evasion and pleaded guilty in January to overbilling the government $265,205 for work he and an employee did for NASA and the Defense Department between 2000 and 2006. Nozette admitted that he used that money to help pay personal credit card bills, car loans and maintenance costs for his swimming pool. He faced at least two years in prison under federal sentencing guidelines, according to the plea papers. The documents were sealed because Nozette was cooperating with authorities in unrelated investigations of government corruption, court records show."
