WASHINGTON, DC -- The White House was bathed in blue lights Monday evening in recognition of Peace Officer's Memorial Day.

The color blue is in honor of police officers who have been killed and disabled during the line of duty.

President Donald Trump proclaimed Monday, May 15, as Peace Officers Memorial Day and this entire week, as Police week.

Here is what White House press secretary had to say in his Monday press briefing, regarding President Donald Trump's and Vice President Mike Pence's participation:

"This morning, the President and the Vice President joined tens of thousands of officers and friends of law enforcement at the annual Peace Officers Memorial Service at the United States Capitol. This is the 36th year that the Paternal Order of Police has honored the memory of the brave men and women who have lost their lives in the line of duty with this service and ceremony.

"In the Vice President’s opening remarks, he reiterated the Trump administration’s commitment to standing with the men and women of law enforcement “without apology.” And the President said that these men and women are “the Thin Blue Line between civilization and chaos. Words cannot express the depth of our gratitude.” But he hopes that the actions of this administration will show our men and women in blue “how deeply we care and how strongly we feel about protecting those who protect us all.”

"Earlier today, the President had the honor of meeting with officers and guests from police departments that recently suffered the loss of a police officer from Ulster County Sheriff’s Department, Phoenix Police Department, and the New State Troopers. He also signed a proclamation in honor of Peace Officers Memorial Day and National Police Week."
