President Trump renewed his call Wednesday for anyone convicted of killing a police officer should receive the death penalty.

"The ambushes and attacks on our police must end, and they must end right now," Trump said a National Peace Officers’ Day memorial. "We believe that criminals who murder police officers should immediately, but with a trial, get the death penalty. But quickly. The trial should go fast. It’s got to be fair, but it’s got to go fast."

Trump first made the suggestion during the 2016 campaign at a campaign rally in New Hampshire. Though at that time Trump vowed it would be one of his first actions and would be completed via executive order.

“One of the first things I’d do in terms of executive order, if I win, will be to sign a strong, strong statement that would go out to the country, out to the world, anybody killing a policeman, a policewoman, a police officer, anybody killing a police officer, the death penalty is going to happen,” he said. “We can’t let this go."

Trump has long seemed to be a supporter of the death penalty as he also looked for that result in the case of the Central Park 5, even holding that stance after DNA evidence cleared the Five Black boys.

Trump also called Wednesday to stop immigrants from entering the country illegally after Newman, Calif. officer Ronil Singh was shot and killed during a traffic stop by a man suspected to be in the country illegally. President Trump offered that Singh's death could have been prevented "with border security, with the wall, with whatever the hell it takes."
