RICHMOND — The Virginia Board of Elections has fined Republican lieutenant gubernatorial candidate E.W. Jackson for failing to disclose a $25,000 loan to his campaign in a timely fashion.

The loan was reported in the 61-year-old Chesapeake minister’s latest campaign finance disclosure on Monday, but Jackson should have reported it nearly a month earlier. State law requires that candidates report contributions or loans of $5,000 or more by 5 p.m. the following day in the 12 days prior to a nominating event.

Jackson, who won the GOP lieutenant governor nomination at the state party convention on May 18, received the loan from Charlottesville lawyer Donald Lee Woodsmall on May 8. Jackson reported the loan on June 3.

The elections board issued a fine for $100 on Tuesday. The Washington Post learned of the penalty through an inquiry into Jackson’s campaign finance report.

For the period starting April 1 and ending May 29, Jackson reported raising more than $120,000 — including the $25,000 loan. The remaining $95,000 in donations listed “Jackson for Lt. Gov.” as the sole donor and the contributions were not itemized as required by state law.

Jackson’s report noted that an amended version will be submitted later. State law requires that all committees itemize, on each report, contributors whose total exceeds $100. The law grants the elections board 21 days to review each report for completeness and notify the committee of any missing information.

Neither Jackson nor his campaign has responded to repeated telephone and e-mail inquiries regarding the campaign filing.

In an interview with The Washington Post on Sunday, Jackson said his campaign is in the process of “transitioning from convention to general election mode.”
