Facebook CEO Mark Zuckerberg and wife Priscilla Chan have hired Joel Benenson, former pollster for former President Barack Obama and chief strategist for Hillary Clinton's 2016 presidential campaign, as a consultant, according to a report on Wednesday.

Joel Benenson's company, Benenson Strategy Group, will be conducting research for the Chan-Zuckerberg Initiative, the couple's philanthropic group, according to Politico. The initiative is dedicating to "advancing human potential and promoting equal opportunity."

Zuckerberg and Chan announced in 2015 that they would be giving 99 percent of their Facebook shares, estimated at $45 billion, to charity.

David Plouffe, manager of Obama's 2008 presidential campaigned also joined the Chan-Zuckerberg Initiative this year to lead policy and advocacy work.

"My job will be to find creative ways to lift the voices of those who want to build a better future – no matter where they live, their background, or their ideology," Plouffe wrote in a Facebook post that announced the January move.

Earlier this year, Zuckerberg set out to visit every state in the U.S., fueling speculation that he might run for president in 2020. Zuckerberg denied having any political ambitions in a Facebook post.

"Some of you have asked if this challenge means I'm running for public office. I'm not," Zuckerberg said. "I'm doing it to get a broader perspective to make sure we're best serving our community of almost 2 billion people at Facebook and doing the best work to promote equal opportunity at the Chan-Zuckerberg Initiative."

Benenson Strategy Group did not immediately responded to a request for comment.
