President Trump lit the White House in blue Monday night in honor of Peace Officers Memorial Day.

The move kicks off Police Week, which honors the 118 officers who died and 66 others who were injured in the line of duty in 2016. Those numbers were up 40 percent from 2015.

Trump visited the U.S. Capitol earlier Monday to pay tribute to all law enforcement officers and gave remarks at an event held on the west lawn of the building.

Former President Barack Obama lit the White House in rainbow colors after the Supreme Court ruling that allowed same-sex couples nationwide to marry in June 2015.

Following the attack on police officers in Dallas last July, the Federal Law Enforcement Officers Association Foundation asked Obama to illuminate the White House in blue in honor of the five fallen officers. Obama ordered flags to be flown half-mast, but did not light up the 1600 Pennsylvania Avenue NW building.

One of Trump's campaign promises was to return "law and order" to the country. He pledged to be a strong supporter of law enforcement and immigration agents.

Monday's lighting is not the first time Trump lit the White House. He previously lit up the People's House in early April in honor of World Autism Awareness Day.
