Billionaire hedge-fund founder Ken Griffin, who played an outsized role in funding Gov. Bruce Rauner’s successful gubernatorial run, has just maxed out his contribution to the Republican National Committee.

A filing with the Federal Elections Commission shows Griffin poured $324,000 — the new allowable maximum — to the RNC.

The donation is small potatoes when compared with the mega-cash infusions he made to Rauner for a total of nearly $13 million.

Griffin broke a record in Illinois when he gave $2.5 million in one transaction to Rauner. Rauner, who was in a highly contentious race against then-Gov. Pat Quinn, was operating in a different environment. Rauner, a multimillionaire, had broken the caps on donation limits by giving more than $250,000 to his campaign.

Rauner eventually went on to invest more than $6 million in his race, and Griffin gave nearly $5 million before the Nov. 4 election.

After Rauner won, Griffin gave an additional $8 million to Rauner, and Rauner gave himself $10 million before being sworn in to office in January.
