Mayor Cherelle Parker is backing the Sixers $1.5 billion arena plan in Center City. Why it matters: Parker's blessing is critical for the stalled project to overcome strong opposition and sends a powerful signal to fellow Democratic lawmakers to fall in line.

The announcement from Philadelphia Mayor Cherelle Parker comes just over a week after hundreds of people gathered at a town hall meeting to either voice their concerns or show their support of the proposed new Sixers Arena.

Jason Kelce didn't hesitate to offer his thoughts on the Philadelphia 76ers' proposed arena in Center City one day after Mayor Cherelle Parker endorsed the controversial project.
