Robert Reich, who served as President Bill Clinton's labor secretary, has endorsed Bernie Sanders for president.

“I endorse Bernie Sanders for president of the United States. He's leading a movement to reclaim America for the many, not the few,” Reich tweeted Friday, elaborating on Facebook a few hours later.


“This extraordinary concentration of income, wealth, and political power at the very top imperils all else – our economy, our democracy, the revival of the American middle class, the prospects for the poor and for people of color, the necessity of slowing and reversing climate change, and a sensible foreign policy not influenced by the “military-industrial complex,” as President Dwight Eisenhower once called it,” Reich wrote.

“It is the fundamental prerequisite: We have little hope of achieving positive change on any front unless the American people are once again in control," he continued.

Reich added that while he holds Hillary Clinton in high regard, he believes Sanders is the best bet for the country's future: “I have the deepest respect and admiration for Hillary Clinton, and if she wins the Democratic primary I’ll work my heart out to help her become president. But I believe Bernie Sanders is the agent of change this nation so desperately needs.”

Reich — who left the Clinton administration in frustration over spending cuts and his lack of influence — has long been outspoken about income inequality and critical of Wall Street. On Wednesday, he wrote that Sanders' rise can largely be attributed to Americans’ dissatisfaction with "the establishment" in Washington.

“The establishment doesn’t get that most Americans couldn’t care less about economic growth because for years they’ve got few of its benefits, while suffering most of its burdens in the forms of lost jobs and lower wages," Reich wrote.

Reich is a professor of Public Policy at the Goldman School of Public Policy at the University of California, Berkeley. A prolific author, he published a memoir of his time in the Clinton administration, "Locked in the Cabinet."
