"Pres. Obama has done a remarkable job in historically difficult circumstances," Freeman wrote.

"He ended combat operations in Iraq, put in place sensible reforms of Wall Street, saved the auto industry and protected the health care of every American. He has led our nation to be more tolerant and placed impressive, accomplished women on the Supreme Court."
