DOJ press release: “According to a statement of facts filed with the plea agreement, Sorenson admitted that he had supported one campaign for the 2012 presidential election, but from October to December 2011, he met and secretly negotiated with a second political campaign to switch his support to that second campaign in exchange for concealed payments that amounted to $73,000.   On Dec. 28, 2011, at a political event in Des Moines, Iowa, Sorenson publicly announced his switch of support and work from one candidate to the other.”

John Gramlich says it was a switch from Michele Bachman to Ron Paul.
