Last week, Chance the Rapper tweeted "Save Chicago. This friday." Immediately, fans began to speculate what the tweet's cryptic message was intended to be. Theories arose that a secret show would be performed in the rapper's home city or that he'd possibly join his younger brother Taylor on stage at the latter's Saturday night concert. Instead, the hip-hop star was actually pointing to a larger concern than his music this Memorial Day weekend.

In a series of tweets, the rapper explained his new movement, why he started it, and how the community can help. 

The movement is also being backed by fellow Chicago native Common, who tweeted out "Great news! @chancetherapper told me that Chicago went 42hrs from Thursday to Saturday w/o 1shooting. Let’s keep it up! #SaveChicago" earlier this week.

What can you do to help #SaveChicago?
