President Trump honored fallen officers at a ceremony in Washington, D.C. on Tuesday, telling stories of some of those who gave their lives.

"Today every American heart bleeds blue," said Trump at the 37th annual National Peace Officers' Memorial Service.

Officers Killed in the Line of Duty in 2018

The president saluted the family of Lt. Aaron Allan, a Southport, Indiana, police officer who was killed in the line of duty last year, leaving behind a six-year-old son. 

Allan, an Air Force veteran, was shot and killed by a man that he was attempting to rescue from an overturned vehicle. 

Next, the president honored Charles Hartfield, a Las Vegas police officer and Army veteran who was killed by a gunman who opened fire from the Mandalay Bay hotel. 

"He gave his life so countless others could live," said Trump, explaining that Hartfield was attending the country music concert with his wife and helped injured concertgoers escape the mass shooting. Hartfield left behind two children. 

The president then called out the family of Border Patrol agent Rogelio "Roger" Martinez of El Paso, Texas. Martinez died along a dangerous part of the southern border in Nov. 2017, leaving behind a son. 

"It was horrific, it was violent and he was brave," said Trump, calling on Congress to secure the border and stop sanctuary policies.

Later in the address, Trump brought onto the stage the family of slain NYPD Det. Miosotis Familia, who was gunned down last summer in an ambush attack as she sat in her police vehicle.

"She was ambushed by a man for the simple reason that she was a member of law enforcement," said Trump. 

Familia, a 12-year veteran of the force, left behind three children. 

"America lost incredible heroes, but they will endure forever," Trump said at the end of the event.
