JIM LEHRER: In other news today, gunfire broke out at the Holocaust Memorial Museum in Washington with hundreds of visitors inside. Police said an elderly man shot and killed a security guard.
NewsHour correspondent Kwame Holman reports.
KWAME HOLMAN: Police said it happened just before 1 p.m., when the gunman walked into the museum and opened fire with a rifle. He shot one guard before being shot in turn by two other guards.
Officials quickly evacuated the museum and cordoned off the surrounding area. Those inside told of hearing shots and then being ordered to get down.
DAVID UNROE: First shot, I -- you know, you don't expect that. You're in a secure place, place of reverence and respect, you don't expect gunshots. So -- but then as they repeated, it's like, "That's gunfire." And then they said, "Hit the floor," and we did.
KWAME HOLMAN: The wounded guard died later at a Washington hospital. The suspect was listed in critical condition.
The Holocaust Museum is one of the most popular sites in Washington, with more than 1.5 million visitors a year. Security is tight. Museum-goers must pass through metal detectors and have their bags searched. Police say today's shooting took place outside a security checkpoint.
It was widely reported the gunman was James von Brunn, a white supremacist who is 88 years old. He runs a racist, anti-Semitic Web site and was convicted in 1983 of trying to kidnap members of the Federal Reserve Board.
But Washington, D.C., Police Chief Cathy Lanier said there's no sign today's incident was part of any larger plot.
CHIEF CATHY LANIER, Washington, D.C., Police Department: We had no prior information. There was no prior threats of this nature about this incident. So it appears to be a lone gunman who entered the museum and opened fire with what appears to be a rifle.
KWAME HOLMAN: At the White House a few blocks away, a spokesman said President Obama was "obviously saddened" at the news. Just last week, he visited the site of a Nazi concentration camp in Germany.
