MARGARET WARNER: Still to come on the "NewsHour": now what on the oil spill; the public and the eco-disaster; China's smoking problem; and a Vietnam War story -- but, first, the other news of the day.
Here's Hari Sreenivasan in our newsroom.
HARI SREENIVASAN: This was Memorial Day, and millions of Americans joined in tributes to fallen troops. President Obama paid his respects at Abraham Lincoln National Cemetery outside Chicago, but severe weather forced him to cancel his scheduled remarks.
Outside Washington, Vice President Biden took part in the wreath-laying at Arlington National Cemetery.
U.S. VICE PRESIDENT JOSEPH BIDEN: The only obligation a government has that is truly sacred, our sacred obligation, is to provide these warriors with everything they need to complete their mission and everything they need and, I might add, deserve when they come home.
HARI SREENIVASAN: American troops in Iraq and Afghanistan also paused to remember fallen colleagues. The ceremonies included this service at Bagram Airfield in Afghanistan, led by General Stanley McChrystal, the overall U.S. commander. Officials also unveiled a steel beam from the World Trade Center in New York.
In Central America, Tropical Storm Agatha, the first of the Pacific hurricane season, struck on Saturday, claiming at least 130 lives. More than 94,000 people were evacuated in Guatemala. Rescue workers rushed to look for the missing after heavy rain caused landslides.
Those are some of the day's major stories -- now back to Margaret.
