Breaking ranks with his party’s leaders, Rep. Mark Udall (D-Colo.) said Sunday that Ways and Means Chairman Charlie Rangel (D-N.Y.) should give up his post amid an ethics investigation into his personal finances. “I think it would be helpful if Charles Rangel stepped down,” Udall said on “Meet the Press.” However, he said, “I think it’s his decision whether he steps down or not.” Udall is running against GOP former Rep. Bob Schaffer for an open Senate seat in Colorado. Democratic leaders continue to say that Rangel should keep his post while the House ethics committee investigates his ownership of a Dominican Republic villa, living arrangements, use of House parking facilities and fundraising efforts. The Colorado Democrat praised Rangel for serving “admirably” during the Korean War and said his leadership expertise is needed in Congress. He noted that Rangel himself has called for an ethics investigation into his finances three different times.
