Presidential hopeful Bill Bradley challenged Vice President Al Gore last night to press President Clinton to issue an executive order banning racial profiling. It was the sixth and final debate between the two Democratic presidential candidates before the first votes are cast in the Iowa Caucuses one week from yesterday. Bradley seized the offensive at a debate sponsored by the Iowa Brown/Black Presidential Forum, a group that promotes black and Latino issues, after Gore pledged to sign an executive order himself banning profiling, the practice of singling out African Americans for police questioning. Bradley said, “You know, Al, I know that you would issue an order to end racial profiling if you were president of the US. But we have a president now. You serve with him. I want you to walk down that hallway, walk into his office and say, ‘Sign this executive order today.’”
