Tom Steyer, the billionaire Democratic donor, provided a seven-figure cash infusion for his super PAC in late May, kicking off what will likely be an expensive election cycle for the group.
Steyer wrote NextGen Climate Action a $5 million check on May 28, the group told the Federal Election Commission in a recent filing. The contribution was Steyer’s first donation this year to the group, to which he steered roughly $67 million during the 2014 midterms.
NextGen has received less than $1,800 this year this year from individual contributors other than Steyer, FEC reports show.
Early indications suggest that Steyer will support Hillary Clinton’s presidential campaign. He and his wife held a fundraiser for Clinton last month at their California home.
Most of NextGen’s expenditures this year have gone to its political operations in key battleground states, primarily Iowa and New Hampshire. But in May it also passed along $20,000 to another group, Americans United for Change.
That group, which is part of a network run by the pro-Hillary Clinton political operative David Brock, frequently attacks billionaire political financiers.
