The New Hampshire Attorney General’s office has concluded that Executive Councilor Karen Liot Hill did nothing wrong when she used her government email to assist a law firm that was suing the state over its voter ID law.

Assistant Attorney General Brendan O’Donnell wrote that Liot Hill’s use of her state email to assist a national Democratic law firm find plaintiffs didn’t amount to “electioneering” under state law.

The state Republican party alleged in August that Liot Hill — the only Democrat on the five-member Executive Council — misused her position by involving herself in a lawsuit against the state.

From the start, Liot Hill called that claim baseless, and the Attorney General’s office said Liot Hill’s conduct didn’t warrant sanction.

“This Office cannot conclude that the e-mails constituted a misuse of position or otherwise violated the executive branch ethics code. This matter is closed,” the office wrote.

In a statement Friday, Liot Hill, from Lebanon, welcomed the conclusion of the case.

“The AG’s findings underscore the partisan nature of the ongoing attacks against me: I am being impeached not for wrong-doing, but for being a Democrat,” she said.

The lawsuit challenging New Hampshire’s voter ID recently failed in state court. But this issue may not yet be over: A top House Republican has filed a bill to explore Liot Hill’s impeachment next year.

As the lone Democrat on the Executive Council, Liot Hill is her party’s ranking member in the State House. That profile has made Liot Hill, who spent two decades in local politics before winning election to the council last year, a regular target for Republicans, who argue that her approach to the job, which she says honors the state’s volunteer spirit, has crossed ethical lines.

The New Hampshire Republican Party did not immediately respond to a request for comment to the Attorney General report Friday afternoon.
