ALEXANDRIA, Va. (AP) — A Virginia man who managed a losing congressional campaign while running a so-called Super PAC has pleaded guilty to illegally funneling money from the PAC to bolster his candidate’s campaign.

Federal prosecutors said it is the first time a person has been convicted of illegally coordinating campaign contributions between political committees.

Thirty-four-year-old Tyler Harber of Alexandria was campaign manager and political consultant for Chris Perkins, who ran in 2012 as a Republican against Democratic incumbent Gerry Connolly in a northern Virginia district.

At a plea hearing Thursday in federal court, Harber admitted causing the PAC, which is not named in court records, to spend $325,000 in ads targeting Connolly.

Super PACs can solicit and spend unlimited amounts of funds, but cannot coordinate their activity with specific congressional candidates.
