President George W. Bush praised U.S. troops on Saturday and gave a special thank-you to military families who have turned the grief of losing loved ones into acts of compassion, according to AP. For many relatives of U.S. troops, military service means packing up their belongings and moving on short notice, living in a foreign country or missing a family member as he or she serves overseas, Bush said in his weekly radio address. Bush taped his broadcast on Friday before leaving aboard the Marine One presidential helicopter to fly to Camp David with first lady Laura Bush; their daughter Jenna; and Mrs. Bush's mother, Jenna Welch.
