Rep. James Comer (R-KY) accused President Donald Trump of sinking GOP candidates ahead of the midterms, according to a news outlet that labeled him a "dimwit" for doing so.

During a Fox News interview, Comer complained that donations to individual Republican candidates are dwindling as money piles up in Trump's MAGA Inc. Super PAC.

"A lot of the individual members' online donations are down because more of the small-dollar donors have gravitated towards MAGA Inc.," Comer lamented on Fox News.

Comer, who chairs the House Oversight Committee, is one of the most prominent Republicans to voice concern on the record about the fundraising imbalance. MAGA Inc., as a super PAC, can raise unlimited sums from donors but is legally barred from coordinating directly with the campaigns it supports, which shapes how and when such money reaches individual races.

The New Republic responded by calling Comer a "MAGA Dimwit," arguing that he had effectively admitted Trump "is harming their midterm hopes."

MAGA Inc. has spent only a small portion of its funds on midterm races, including for Sen. Darline Graham Nordone (R-SC). On Friday, however, Trump touted that the Super PAC has raised close to $1 billion.

"We're going to need every penny of it," Comer said on Fox News.

Other Republicans have echoed Comer's hope that Trump will spend more, according to The New Republic. On Friday, Trump said he plans to do so and touted a planned campaign tour to boost GOP candidates in competitive races during the final month of the midterms.

Comer insisted during the appearance that he was not criticizing Trump, and he praised how "well" the president has "managed" his Super PAC money by not yet spending any of it, according to The New Republic.

"Comer shed light on a deeper way that Trump is screwing his party," The New Republic argued. "If small donors are giving to MAGA Inc. to the exclusion of Republicans, it's in no small part because Trump is helping make that happen."

The New Republic noted that Trump has "repeatedly" declared that the GOP "failed him" instead, and pointed out that Trump recently elevated the claim that the party has let him down by continuing to "slow walk" his agenda.

How much of the roughly $1 billion MAGA Inc. ultimately directs toward competitive midterm races, and when, remains a central question for Republican candidates counting on that support in the campaign's closing stretch.
