Officials in Flint have been asked to produce documents and audio and video recordings as part of a federal probe into at least $1.3 million in grant spending by the city.
The Flint Journal is reporting through a Freedom of Information Act request that it has learned federal officials have subpoenaed the records from four city departments.
Documents, check stubs and e-mails from the past two years are being sought. Federal authorities also conducted a May 25 raid at Flint City Hall.
Many of the records requested pertain to city economic development workers and personnel files of two administrators. The newspaper says both administrators cited the investigation and declined to comment.
A federal grand jury was convened July 6.
Mayor Dayne Walling says the city is cooperating in the probe.
