TIGTA has also announced the appointment of two more staff: Ruben Florez is now the assistant inspector general for investigations (AIGI) over field operations, and Jeffrey Long is now the AIGI over the threat, agent safety, and sensitive investigations directorate for TIGTA’s Office of Investigations. The two new employees will provide executive leadership to TIGTA’s investigative operations and headquarters support duty.
