WATCH LIVE: Obama remembers soldiers' sacrifices on Memorial Day

President Barack Obama remembered the service of U.S. military Monday at Arlington National Cemetery, where he placed a wreath on the tomb of the unknown soldier and spoke about soldiers who had lost their lives during service for the country.

Obama also authored an op-ed in the military newspaper Stars and Stripes Monday in which he marked the 50th anniversary of the Vietnam War.

"After Vietnam, our veterans didn’t always receive the respect and thanks they deserved. At times they were neglected and even shunned, which was a national shame," the Obama wrote. "We’ve pledged many times since Vietnam that we would never let that happen again, and that we would give our veterans, especially our Vietnam Veterans, the respect and honor they deserve. This 50th anniversary is our opportunity to do it right."

Obama is also scheduled to remember Vietnam veterans Monday afternoon at the Vietnam War Memorial in Washington, D.C.

Watch the live feed of Obama broadcast via the White House, scheduled to start at 1:50 p.m. Eastern.
