Former Iowa state Sen. Kent Sorenson pleaded guilty to federal charges stemming from his switch of support from one Republican candidate for president to another before the 2012 caucus campaign.
In a Justice Department news release, federal officials say the 42-year-old Milo Republican received "under-the-table payments" when he changed loyalties in the campaign's closing days.
Although Justice officials wouldn't say, Sorenson was the state chairman for U.S. Rep. Michele Bachmann's campaign beginning in June 2011. He admitted receiving and lying about monthly payments of roughly $8,000 from another campaign from October to December. Six days before the Jan. 3 caucuses, Sorenson declared his support for then-U.S. Rep. Ron Paul.
Sorenson pleaded guilty to causing a campaign to falsely report expenditures and obstruction.
A call to Sorenson wasn't immediately returned.
