On Capitol Hill, the Senate Judiciary Committee has concluded its nomination hearing for Supreme Court Chief Justice nominee John Roberts.The committee is expected to vote on Roberts next week. Near the end of the hearing Roberts said, “If you’ve looked at what I’ve done since I took the judicial oath that should convince you that I’m not an ideologue.” On Thursday Republican and Democratic Senators called a series of witnesses to testify about Roberts’s character. Long time civil rights leader and Democratic Congressman John Lewis warned that the confirmation of Roberts would be a setback to civil rights. Carol Browner, the former head of the Environmental Protection Agency under Clinton, also criticized Roberts. So did Marcia Greenberger, co-president of the National Women’s Law Center. Among the witnesses who supported Roberts were former Michigan Gov. John Engler who now heads the National Association of Manufacturers. Engler said he expects Roberts would add a business-friendly voice to the court. Meanwhile Democratic Senators continued to criticize Roberts for refusing to answer dozens of questions about his judicial beliefs. The Coalition for a Fair & Independent Judiciary began airing tv ads on Thursday that highlight Roberts’ refusal to answer many questions.
