Senate Minority Leader Mitch McConnell may have a degree of influence within the Republican National Committee as a high-ranking Republican officeholder, but he does not have any direct control over its spending. The Committee is run by a chair along with an executive committee elected by party members and officials, who in turn approve budgets.
Ronna McDaniel, an early supporter of Donald Trump, became the RNC Chair after Trump’s 2016 victory. In January 2020, she ran unopposed and won another term. In a recent Associated Press interview she said “the party has to stay neutral” in 2024 presidential primaries regardless of whether Trump decides to run again.
The RNC raised $890 million in the 2020 cycle, and as of Feb. 19 had $80.5 million on hand.
