The subpoenas add to a widening review of public funding, but officials have not said what records they are seeking or what prompted the requests. The development came less than two weeks after council members called for an independent audit of Community on the Frontline and Joan’s House, another nonprofit that received a $4 million grant.

There has been no confirmation that Joan’s House was subpoenaed. Its grant is under review because of ties to Councilmember Ed Burroughs. Community on the Frontline was founded by a close friend of Council Chair Krystal Oriadha.

Councilmember Jolene Ivey has called for a clear accounting of how the grants were approved and where the money went. “We all want to get to the bottom of this and to know how did the money get there, what has happened to it since then and how did it happen in the first place,” Ivey said.

County Executive Aisha Braveboy said Thursday that the California-based Edward Charles Foundation had returned more than $7.6 million connected to Community on the Frontline. She said the remaining funds were expected to be returned within days. The total recovered and the distribution of the funds remain unresolved questions.

Of the roughly $8.6 million awarded to Community on the Frontline, nearly $764,000 had been spent, according to reporting cited in the available information. About $7.8 million remained with the Edward Charles Foundation or another organization.

The subpoenas could help establish how the grants were approved, where the funds went and whether county rules were followed. Their scope and any findings have not been made public. The FBI has declined to confirm whether it is involved in an investigation in the county.
