Arraignment set after showdown near White House

A man in a van, who held authorities at bay for more than four hours near the White House after threatening to ignite a substance inside the vehicle, will be arraigned in U.S. District Court Wednesday morning, metropolitan police said. An FBI official said the incident appeared to be related to a domestic dispute, not terrorism. The official said they were eventually able to negotiate with the man, a disgruntled Vietnam veteran, who decided to turn himself in. It was not immediately clear what, if any, type of substance was in the van. According to officials, the man has been identified as John Kerry, 61 of Massachusetts.
