America's fallen heroes honored with Memorial Day ceremonies across nation's capital

America's fallen heroes were honored at monuments and memorials across the nation's capital on Monday as Memorial Day services took place throughout the D.C. region.

Visitors gathered at the United States Marine Corps War Memorial and at the Tomb of the Unknown Soldier at Arlington National Cemetery to pay their respects. Veterans attended a special wreath ceremony at the World War II Memorial.

Vice President Mike Pence paid tribute to fallen members of the U.S. Armed Forces, thanking their loved ones in a ceremony at Arlington National Cemetery and acknowledging that for them "every day is Memorial Day." Pence placed a wreath at the Tomb of the Unknown Soldier to remember dead service members whose remains haven't been identified and observed a moment of silence. He told Gold Star families he was honored by their presence.

President Donald Trump and Melania Trump visited the Arlington, Virginia, cemetery last week and placed flags at several gravesites, a decades-old tradition known as "flags in." Trump is in Japan , where he's expected to address troops aboard a battleship.

The National Memorial Day Parade, which is held annually along Constitution Avenue in D.C., honors the sacrifices of those who died. The 2019 parade commemorates the 75th anniversary of D-Day and also will features surviving members of the 6888th Central Postal Directory Battalion -- the only battalion of African-American women to deploy overseas during World War II.
