  • Senator Kirk un-endorses Donald Trump

Senator Mark Kirk has decided to withdraw his earlier support of controversial presumptive GOP presidential nominee Donald Trump. “After much consideration, I have concluded that Donald Trump has not demonstrated the temperament necessary to assume the greatest office in the world,” he said in a statement. The moderate Republican is facing a tough challenge from U.S. rep Tammy Duckworth, and the seat is considered one of the most vulnerable in the upcoming election. Kirk isn’t the only Republican senator refusing to support Trump; South Carolina senator Lindsey Graham won’t get behind his candidacy either.   [Sun-Times]

The recent wave of gun violence is so severe that a famous rapper got a court hearing postponed because he’s concerned about a retaliatory shooting if he travels to Chicago. The Game, who is based in Los Angeles, is facing a $10 million sexual-assault lawsuit here, and the alleged victim didn’t oppose the request. The judge in the case hasn’t decided on a new date.
