Former White House spokesman Bobby Whithorne is joining billionaire Tom Steyer's climate action group.
Whithorne, who first joined the White House in 2011 and announced his departure in mid-June, wrote in an email Wednesday he would be joining the California-based NextGen Climate.
"I’m pleased to join the team and look forward to working for an organization that’s focused on bringing climate change to the forefront of the political discussion," Whithorne said in an email to The Hill. "They have an all-star team working on races in 2014, and I feel fortunate to be a part of this effort."
Steyer's group shot to the forefront of the political scene in the last year, and is attempting to make climate change a wedge issue in the 2014 midterms.
NextGen Climate boasts a team of strategists who come from every "winning" Democratic presidential campaign over the last 30 years.
Steyer, a former hedge fund manager, visited the White House last week to meet with administration officials about a new report from his joint venture with New York Mayor Michael Bloomberg, Risky Business, which detailed the financial risks of climate change.
Republicans have slammed the White House and congressional Democrats for their ties to the billionaire, claiming his donations have pushed lawmakers into pursuing "radical" climate policies.
