The National Public Pension Coalition, an organization representing millions of teachers, nurses, police, firefighters and other public sector employees released a statement this week on a recent Pew Research Center report.

"To the detriment of all public employees and all of our communities, 'The Widening Gap Update' uses data from fiscal year 2010 and will undoubtedly be used by organizations and individuals like the Koch Brothers and Arnold Foundation to advance their own agendas against public employees," the organization said in a statement.

"No one is more interested in the long-term solvency of retirement systems than public employees, who are taxpayers themselves and who rely on their modest pension benefits after putting their own life savings into these plans. It's simply unfair to repeatedly punish our teachers, nurses, police officers, and other public employees, many of whom do not receive Social Security."
