Vice President Dick Cheney, Secretary of State Condoleezza Rice and Defense Secretary Robert Gates were all in attendance. The president also received some uninvited guests. Peace mom Cindy Sheehan and four other antiwar activists were arrested at a barricade on the president’s ranch. Sheehan said she wanted to display a “peace surge” as the White House moves toward a “troop surge” in Iraq. Sheehan’s son Casey was killed in Iraq in April 2004.
