RICHMOND, Va. (AP) — The FBI is investigating the circumstances of former Democratic state Sen. Phil Puckett’s departure from the General Assembly, according to a person with direct knowledge of the probe and a state official.

The Richmond Times-Dispatch first reported the federal investigation into Puckett’s resignation, a move that gave control of the state Senate to Republicans and dealt a serious setback to Gov. Terry McAuliffe’s push to expand Medicaid eligibility.
