Kerry's staff has made Teresa apologize: ""I had forgotten that Mrs. Bush had worked as a school teacher and librarian, and there couldn't be a more important job than teaching our children. As someone who has been both a full time mom and full time in workforce, I know we all have valuable experiences that shape who we are. I appreciate and honor Mrs. Bush's service to the country as First Lady, and am sincerely sorry I had not remembered her important work in the past."
