Tensions between Ron DeSantis’ struggling presidential campaign and his allied super PAC are boiling over, with the campaign losing confidence in Never Back Down’s leadership and ability to orchestrate a TV advertising campaign, according to two people close to the Florida governor.

The criticism comes amid mounting questions about the strength of DeSantis’ campaign, and that of Never Back Down. The super PAC has suffered two major departures over the last week, with the organization’s CEO, Chris Jankowski, and its chair, Adam Laxalt, stepping down.

Earlier this week, DeSantis campaign manager, James Uthmeier, wrote a memo to donors in which he praised Never Back Down for its field operation and urged the group to focus on that going forward. But he implicitly suggested a newly formed pro-DeSantis super PAC, Fight Right, take the lead on TV advertising. Campaign officials believe the PAC’s TV ads have been ineffective, according to two people close to DeSantis and granted anonymity to speak freely.

“The campaign doesn’t think NBD’s current interim leadership should be within a mile of a TV budget,” said one of the people close to DeSantis.
