"The officers were through their various context, were trying to say, the Congressman actually invited us in and he's lying now. Bobby Rush is a former Black Panther. He didn't invite the police into his office. And the fact that they would even say that, and even assuming that was true, five hours, when literally murder and mayhem is happening everywhere, police officers are getting the crap beaten out of them, being called to officer distress, and you take a siesta for five hours? That's outrageous. And the fact that even in this moment, as shameful as this context is, there are people who are literally saying, making excuses and saying we're being too harsh. No, no, no. We have not been too harsh," Lightfoot told CNN host Anderson Cooper on Thursday.
