A stomach ailment forced U.S. President George W. Bush to miss some meetings at an international summit on Friday, but after resting in his room, he rejoined the gathering and prepared for talks in Poland on a missile defense system, REPORTED AP. «He feels well enough to continue with his full activities,» White House counselor Dan Bartlett told reporters. «He feels terrible about any disruption he may have caused.» Even while ill, Bush taped his radio address, met as planned with France's new president and prepared for talks in Poland on a missile defense system. The president was already dressed when he began feeling ill in the morning, Bartlett said. The aide said Bush's illness was «probably more viral in nature» and did not appear to be the result of anything he ate at the summit of eight industrialized democracies being held at a luxury resort here. Bush stayed in bed for several hours to rest and recuperate. He missed one session with African leaders and another with leaders from China, India, Brazil, Mexico and South Africa, all developing nations, not G-8 members. He returned to the talks in time for the closing lunch. Bush was «fully expected» to keep to his original travel itinerary, Bartlett said. Bush was scheduled to fly from Germany to Poland to meet and have dinner with Polish President Lech Kaczynski and then on to Rome.
