CRAWFORD, Texas -- Iraq war protester Cindy Sheehan said Friday she plans to expand her focus to Congress, starting with House Majority Leader Tom DeLay, a Bush ally and fellow Texan. Sheehan has been camped outside the president's Crawford, Texas, ranch this month, seeking a meeting with him to discuss the U.S. presence in Iraq, where her son was killed in 2004. She plans to begin a bus tour on Thursday to the White House to campaign for the withdrawal of U.S. troops from Iraq.
