More than 2,000 residents are under an evacuation order after a large fire broke out at an Indiana recycling plant on Tuesday afternoon, officials said. During a telephone interview with ABC News on Tuesday, Richmond Mayor Dave Snow called the fire a "worst-case scenario" and voiced concern for the air quality in the city, which is home to more than 35,000 people. Richmond resident Brad Walton described what smelled like burning tires from his home, located about five miles from the fire
