Two Democratic senators are calling on Supreme Court nominee John Roberts to explain before his confirmation hearings why he continued to judge a lawsuit against the Bush administration while being interviewed to be a justice. In that case, Roberts ruled in favor of the Bush administration on a case that said the Bush administration could deny Guantanamo prisoners constitutional rights they would theoretically have in US courts. Senators Charles Schumer of New York and Russ Feingold of Wisconsin wrote a letter to Roberts, saying Roberts’ answers will determine whether they bring the issue up at his confirmation hearings beginning Sept. 6.
