The timing of Puckett’s resignation and the circumstances of his tobacco job offer — which Puckett subsequently chose not to pursue — not only drew strong criticism from his own party, but the matter is under federal investigation.

A federal grand jury heard evidence in Abingdon last week, reviewing, among other things, the emails outlining the Puckett job promise.

Republicans, stung by Democratic accusations that they used a potential job offer to encourage Puckett to leave, have fired back, suggesting the federal investigation is politically motivated. McAuliffe’s appointments of Brink, Howell and Marsh, they charged, should be subject to similar scrutiny.

“The Puckett precedent is clear: resigning General Assembly to take a government job — or even to consider taking a government job — is worthy of empanelling a grand jury,” said Pat Mullins, chairman of the Republican Party of Virginia.

Unlike Puckett’s seat, in a district that leans heavily Republican, all three of the departing Democrats hold seats that are considered solidly within party control. Their departure from the General Assembly, and the timing of their exit, will not tilt the balance of power in the legislature or have an impact on any pending legislative matter.
