Story highlights Trey McCarley, Kris Money and Debbie Aleksander are no longer with the campaign

Bush and his super PAC have amassed the most impressive fundraising haul of any Republican candidate thus far

Washington (CNN) Personality conflicts may have led to three top Jeb Bush fundraisers leaving the campaign, but they are still working with the former Florida governor's super PAC.

Trey McCarley, Kris Money and Debbie Aleksander are no longer with the campaign, but now working with Bush's super PAC, Right to Rise.

"It's a large finance operation with a lot of consultants around the country. Fundraisers tend to be hard-charging and assertive. Personality conflicts happen. Trey, Kris and Debbie are good people and seasoned fundraising professionals," said Ana Navarro, a Republican strategist and CNN political analyst, told CNN. "They've done a good job. That they're still working for the super PAC tells us it's not a Jeb issue."

Navarro, who is supporting Bush in the 2016 election, was Bush's first director of immigration policy during his time as Florida's governor.

Bush spokesman Tim Miller would not comment on the specific departures, but told CNN Bush has the deepest and widest fundraising operation of any candidate in the field, noting that longtime consultant Ann Herberger is leading the operation with more than two decades of experience.
