U.S. PRESIDENT GEORGE W. BUSH MADE HIS SECOND VISIT TO BAGHDAD SINCE THE 2003 INVASION ON TUESDAY, DAYS AFTER U.S. FORCES KILLED AL QAEDA'S CHIEF IN IRAQ, REUTERS REPORTED. "GOOD TO SEE YOU," IRAQ'S NEW PRIME MINISTER NURI AL-MALIKI TOLD BUSH AS THEY SHOOK HANDS IN ONE OF SADDAM HUSSEIN'S OLD PALACES. "THANKS FOR HAVING ME," BUSH REPLIED. THE WHITE HOUSE SAID BUSH WOULD BE ON THE GROUND FOR MORE THAN FIVE HOURS AND WOULD ALSO MEET U.S. TROOPS DURING THE SURPRISE TRIP, BEGUN IN HIGH SECRECY. THE VISIT, HIS FIRST SINCE NOVEMBER 2003 WHEN HE WENT TO SEE U.S. TROOPS FOR THANKSGIVING, COMES SIX DAYS AFTER A U.S. AIR STRIKE KILLED ABU MUSAB AL-ZARQAWI, LEADER OF AL QAEDA IN IRAQ.
