Reached by phone, Lundergan referred questions to his legal team.
J. Guthrie True, a lawyer for Lundergan, said his client plans to appeal.
“We are disappointed in the verdict but we understood from the outset that the deck would be stacked against us with prejudicial evidence that we believe was erroneously admitted,” True said in a statement. He added that Lundergan’s team is “confident that the campaign finance laws have been improperly applied in this case and that Mr. Lundergan will ultimately be vindicated.”
Grimes’s office did not immediately respond to an emailed request for comment.
The Lundergans are one of the most prominent families in Kentucky Democratic politics. In addition to serving twice as state Democratic Party chairman, Lundergan also served in the Kentucky state House. He has had a long-standing political rivalry with another Kentucky Democratic stalwart, former governor Steve Beshear.
Thursday’s verdict is the latest political setback for Grimes, who had been viewed as a rising star in the Democratic Party even after her 2014 loss to McConnell. She was among the speakers at the 2016 Democratic National Convention and sharply criticized Sen. Rand Paul (R-Ky.) for running for reelection at the same time that he pursued a presidential bid.
But earlier this year, Grimes began to run into trouble. ProPublica and the Herald-Leader published reports detailing accusations of a power grab by Grimes on the state Board of Elections. Grimes’s office also allegedly used the state’s voter registration system for partisan purposes. Grimes has denied the allegations.
Grimes’s office is under investigation by three state agencies, and in March, the Kentucky legislature passed a measure limiting Grimes’s authority over state elections.
