Terrible news from Washington D.C., as a gunman has opened fire at the National Holocaust Museum on Wednesday afternoon. One security guard was killed in the attack, and the gunman was hospitalized after exchanging fire. The gunman, reported to be James Wenneker von Brunn, is an 89-year-old with links to white supremacy groups. He was seen with a rifle. A third person was injured by broken glass. The Holocaust museum, which draws nearly 2 million visitors annually, requires guests to pass through metal detectors.
