The address is scheduled for 9 p.m. EST at McCormick Place, a convention center along Lake Michigan.
Obama will be joined by the first lady as well as Vice President Joe Biden and his wife, Jill.
The speech is open to the public, but tickets were required. For the chance to see Obama in person, thousands of people stood for hours Saturday in single-digit temperatures in a line that snaked around the convention center, hoping to score a ticket.
