Federal prosecutors have charged three people who worked for Ron Paul's 2012 presidential campaign with conspiring to buy the support of a former Iowa state senator.
Among those changed is Jesse Benton, who now heads up a super PAC supporting the 2016 presidential candidacy of Paul's son, Kentucky Sen. Rand Paul.
An indictment unsealed Wednesday charges Benton, John Tate and Dimitrios Kesari with conspiracy and several other related crimes.
The indictment says they negotiated with former Iowa State Sen. Kent Sorenson to switch his support to Ron Paul in exchange for money. Sorenson had previously backed Minnesota Rep. Michele Bachmann.
The indictment says the arrangement was concealed from Ron Paul himself and that Benton initiated the deal.
