Mayor Rahm Emanuel is pushing hard for Chicago to land Amazon's new headquarters and says the city has everything the company needs.
The sprawling Old Main Post Office building, which has remained vacant over Congress and the Eisenhower Expressway for 20 years, is one of the city's top candidates for Amazon’s second headquarters -- and its promised 50,000 jobs.
Amazon says it needs a half-million square feet on Day 1, and the post office's developers say they have 2.7 million available now with the ability to expand. After removing 23 million pounds of debris, developers say the old post office will be ready when Amazon needs it.
Here's a look inside the building as Emanuel toured it with developers.
