U.S. federal investigators have reportedly subpoenaed Yale University records detailing the school's use of research grants during the past decade.
The Defense Department, the National Science Foundation and the Department of Health and Human Services requested the documents after an audit revealed possible expense padding for stem-cell research, The Wall Street Journal reported Wednesday.
The president of the New Haven, Conn., school, Richard Levin, said faculty and staff have been told to give "top priority" to the requests.
"Regardless of the outcome of the current investigation, we must get all our processes right and make sure that we are good stewards of the funds entrusted to us by the federal government," Levin said.
The agencies and Yale declined to comment on the nature of the grants under scrutiny or why the Pentagon is involved, the Journal reported.
