Former President George W. Bush says he and former First Lady Laura Bush feel "deep sadness" over the chaos unfolding in Afghanistan. The man who, as president sent the first U.S. troops into Afghanistan to root out al-Qaeda terrorists 20 years ago, said he and his wife have been watching the tragic events. Bush said in a statement issued late Monday, "Our hearts are heavy for both the Afghan people who have suffered so much and for the Americans and NATO allies who have sacrificed so much."
