There are different versions of what transpired. The Florida-based fundraising consultants — Kris Money, Trey McCarley, and Debbie Alexander — have said that they voluntarily quit the campaign and were still working with Bush’s super PAC, Right to Rise Super PAC. Others said the three, who worked under the same contract, were let go because they were no longer needed for the current phase of the campaign.

None of the three immediately responded to requests for comment. Bush spokesman Tim Miller would only say that “Governor Bush has the widest and deepest fundraising operation of any candidate in the field. Ann Herberger — a longtime aide with more than two decades of experience in state and national politics — will continue to lead the operation in Florida with our team in Miami.”

One source attributed the departures to personality conflicts in the campaign, some involving Bush’s finance team.

“They were glad to go. This wasn’t a shock to anybody,” said one campaign source. “There were just some personality problems. It happens when you have a big organization like this, a big campaign. Some of the national people are tough to work for.”
