U.S. President George W. Bush will give a national address on from the White House on Monday evening to mark the five year anniversary of the September 11, 2001 attacks, his spokesman said today. At 9 pm EST, Bush will deliver what his spokesman Tony Snow described as a non-political speech about what September 11th has meant to the nation. The speech will be Bush's fifth address to the nation from the Oval Office. His first was on the day of the attacks, just hours after airliners crashed into the World Trade Center and Pentagon. It will be appropriately respectful of those who suffered losses, and optimistic about the strength of a society that can withstand such attacks, Snow said. On Sunday and Monday, Bush plans to visit the sites hit five years ago. He will visit Ground Zero in New York City, where the World Trade Center once stood; the field in Pennsylvania where a passenger uprising brought down one of the planes; and the Pentagon.
