US Senator: Sunnis must be involved in Iraqi gov't

Sen. Barack Obama on Saturday said the United States won't be successful in Iraq unless the political landscape better represents the country's minorities. Obama, the nation's only black senator, met with US Ambassador Zalmay Khalilzad and Iraqi President Jalal Talabani on Saturday. He said before his two-day trip to Iraq that he wanted to ask US commanders what a realistic time frame was for bringing troops home.
