FBI Seizes Guggenheim Exec Phone in Probe Linked to Mark Walter
Federal prosecutors are widening scrutiny of Mark Walter’s business empire after the FBI seized the phone of Guggenheim Investments president Dina DiLorenzo in September, the same day Walter’s own devices were seized, as part of a probe into whether Guggenheim Investments properly records revenue. Authorities also issued subpoenas to insurers controlled by Walter, signaling a broader review of related-party investments across his asset-management and securities holdings. The investigation’s exact stage remains unclear.
