The tension inside the Chicago rap scene is building, especially after the events surrounding last night's murder of local rapper JoJo, and the reaction to his death on Twitter. And now, Chief Keef has taken to Twitter to diss fellow Chi-Town rapper Lupe Fiasco, who last week was quoted saying "Chief Keef scares me" in an interview with 92 Q Jams, in reference to the many murders that have taken place in Chicago this summer and what Lupe called "the culture that [Chief Keef] represents."

Read Chief Keef's tweet directed at Lupe, and Lupe's response below. Also, Odd Future rapper Earl Sweatshirt jumped in to share his feelings on Keef's tweet, which you can also see below.
