President Trump on Friday expressed outrage over the continuing violence in Chicago, demanding to know, "What the hell is happening there?"

"What the hell is going on in Chicago? What the hell is happening there?" Trump said at a graduation ceremony at the FBI academy.

The city's homicide rate has skyrocketed in recent years. According to the Chicago Tribune, this past Thanksgiving weekend was its second-most violent in the past several years. By the end of November, at least 3,322 people had been shot in 2017; 690 fewer than in 2016, but more than 1,000 more victims than in 2012, 2013 and 2014 at the same point, according to the newspaper's data.

"For the second year in a row, a person was shot in Chicago every three hours. You don't think these people in this room can stop that? Trump said. "They'd stop it."

Trump called on the nation as a whole to stop the "anti-police sentiment" and said he firmly back the death penalty for people who kill police officers.

"One of my first executive orders as president instructed the Department of Justice to take all necessary steps and legal action to protect law enforcement from acts of violence against them," Trump said.
