President Trump revived his call for the death penalty to be used on criminals who kill police officers.

“The ambushes and attacks on our police must end, and they must end right now,” Trump said Wednesday in a speech for the National Peace Officers’ Memorial Day service.

“We believe that criminals who murder police officers should immediately, but with 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 added.

Trump’s comment is a repeat of his 2016 campaign promise that people who kill police officers should face the death penalty.

‘‘I said that one of the first things I'd do in terms of executive order if I win will be sign a strong, strong statement that will go out to the country, out to the world, that anybody killing policemen, policewomen, police officer, anybody killing a police officer, death penalty is going to happen, OK. Can't go. We can't let this go," Trump said back in 2015 .

While Trump continues to make the promise to give the death penalty to cop killers, he has yet to roll out specific proposals on what his administration will do to encourage its use.

This is the third time Trump has attended the memorial service for fallen police officers, which was held in front of the U.S. Capitol.
