A timeline of Rahm Emanuel's tenure as Mayor of Chicago

Rahm Emanuel, Chicago's 44th mayor, announced Tuesday he would not seek re-election for a third-term in 2019. Here's a look at his time as mayor of the city, during which time he was criticized for his role in the Laquan McDonald shooting video release, sparred with the teachers union and pushed to protect the status of undocumented residents and Chicago's role as a sanctuary city.

Emanuel resigns as President Barack Obama's White House chief of staff.

Prior to this time, Emanuel made his mark on local and national politics. He ran fundraising for Richard M. Daley's first successful mayoral campaign in 1989. Later, he joined the Bill Clinton White House after serving on his 1992 presidential campaign. After a stint working in investment banking, Emanuel was elected to the U.S. House in 2002 and would serve there until January 2009.

It was also a part of future plans to bring a new police training facility to the city's West Side and create a high-speed alternative to travel between O'Hare and the Loop.

The city releases the dashcam video showing a Chicago police officer fatally shooting 17-year-old Laquan McDonald 16 times. The incident, which occurred in October 2014, started a scandal for Emanuel, who activists say was part of a cover-up to hide the video. Earlier in the week, a judge ordered the release of the video. Earlier on this day, Van Dyke was charged in McDonald's murder.

December 1, 2015

In the wake of the Van Dyke video release, Emanuel fires Garry McCarthy, Chicago's top cop. "Now is the time for fresh eyes and new leadership to confront the challenges the department and our community and our city are facing as we go forward." John Escalante was named the interim superintendent as the city's Police Board began the formal process to find a replacement.
