(CNN) – A day after Michele Bachmann's Iowa campaign chairman jumped ship to the Ron Paul campaign, the two sides are still arguing over what transpired before the news broke.
Kent Sorenson was Bachmann's Iowa chairman since early in the campaign, but announced at a Paul event Wednesday he was joining the Texas congressman's campaign only hours after he appeared with Bachmann at one of her events.

Speaking on CNN Thursday, Sorenson categorically denied he ever spoke with Bachmann about an offer of more money from the Ron Paul campaign, a claim Bachmann has repeated in the wake of the shakeup.
"Absolutely not, that conversation never happened," Sorenson said on "CNN Newsroom."
"As much respect as I have for Michele, the fact of the matter is it just didn't happen. I think it is unfortunate they're resorting to these type of tactics," Sorensen said.
Sorensen said the switch came about because he didn't think the Minnesota congresswoman was in the top tier of candidates, and that in his mind Paul was the only contender competitive against Mitt Romney.
"I think it was very clear that that it came down to a race of the two top tier candidates, Mitt Romney and Ron Paul and I believe it is my duty both to my family and to my state to ensure that somebody like Mitt Romney does not walk away in Iowa with a victory," Sorenson said.
Earlier Thursday, Bachmann doubled down on the accusation she first leveled against Sorenson Wednesday night.
"I had a conversation with Kent Sorenson and in the direct conversation that I had with him, he told me he was offered money," Bachmann told reporters in Des Moines.
She continued, "He was offered a lot of money by the Ron Paul campaign to go and associate with the Ron Paul campaign. No one else knows about that conversation other than Kent Sorenson and myself and I know what he said to me about that."
Bachmann said her conversation with Sorenson revealed the Paul campaign intentionally went after her Iowa campaign chairman because they were anxious about their candidate's poll numbers.
"They were losing steam in Iowa, and losing momentum in Iowa, because Iowans eyes were opening up," Bachmann said. "They understood not only was Ron Paul dangerous when it came to foreign policy, but they're understanding now that Ron Paul would be willing to legalize drugs in the United States including heroin and cocaine. Iowans don't want that."
