The decision by former Sen.Tom Daschle, D-S.D., to withdraw his nomination over a furor regarding his handling of his taxes won't be the end to questions about President Obama and his commitment to "changing the culture of Washington."

As Peter Baker of The New York Times wrote today, though Obama signed tougher ethics rules for lobbyists than any of his predecessors, he hasn't talked much about the exceptions  he has made for certain people. They include William Lynn, the former Raytheon lobbyist who has been nominated for the number two job at the Pentagon. "Faced with the perennial clash between campaign rhetoric and Washington reality, Mr. Obama has proved willing to compromise," Baker wrote.

Meanwhile, anyone interested in a primer on how the ethics and lobbying issues are being discussed in Washington may be interested in a segment from PBS's NewsHour on Feb. 2, the night before Daschle withdrew his nomination.

In the segment, ethics lawyer Kenneth Gross squares off against Melanie Sloan, executive director of Citizens for Responsibility and Ethics in Washington, over the issue of the revolving door and why some are so worried about the exceptions Obama has made to his rules.  See video and transcript here.
