ljafJohn Arnold, the billionaire head of hedge fund Centaurus Advisors, sought proposals from PR firms for a national pension reform campaign, according to a report by Reuters.

The Laura and John Arnold Foundation, the philanthropic entity of the former Enron energy trader, released an RFP in September with an April 2015 launch date for a campaign touting an overhaul of public pensions, the news agency said.

Reuters, which said it could not confirm whether a firm was ever hired, noted that Arnold has become the dominant figure driving pension reform efforts and has largely sought to cut benefits, drawing the ire of public sector workers.

"State and local budgets across the nation continue to face considerable financial strain, and the structure of public employee benefits in most states and communities is unsustainable," says the website of the foundation, which "dominates" the pension reform debate, according to Inside Philanthropy.

Former San Antonio TV news reporter Leila Walsh heads communications for the foundation.

Arnold's foundation also focuses on criminal justice and education reform, and research integrity.
