U.S. President Barack Obama’s wife Michelle is joining her husband’s campaign to reform the nation’s health care system. The popular first lady is speaking out for the president’s initiative, which has been losing support. Mrs. Obama says health care reform is a women’s issue. “Women play a unique and increasingly significant role in our families. We know the pain, because we are usually the ones dealing with it,” she said. The first lady spoke Friday to a gathering of women near the White House, and said the state of the U.S. health care system is unacceptable. “For two years on the campaign trail, this was what I heard from women: That they were being crushed, crushed by the current structure of our health care. Crushed,” she said.
