Thank you to my old friend @chuyforcongress and the over 15,000 people who joined us in Grant Park! Chicago understands how change happens in this country. Over 100 years ago, Chicago workers stood up to their employers to say they are not beasts of burden, workers must be treated like human beings and they must have the right to form a union. Our campaign today is not just a campaign for president — it is a movement of millions of people fighting for justice.
