On the Senate floor last night:

I think where this fundraising solicitation crosses the line and where it finds itself in company with some of the partisan attacks that have been made without substance against this nominee is when it goes on to say ‘Click here to contribute to the Democratic senatorial campaign committee’ and making this part of not only a political attack, but a fundraising effort by the Democrats in the United States Senate. That Mr. President, I believe, crosses a line that should not have been crossed and one for which I believe Dr. Rice is entitled to an apology.
To tie the confirmation of the Secretary of State to a fundraising campaign and to propagate misinformation or disinformation about this distinguished nominee, who is an American success story, in an effort to raise money for the Democratic senatorial committee is inappropriate and I think would offend and does offend the American people, and this offense, I believe, deserves a quick repudiation by our colleagues on the other side of the aisle, who maybe weren’t involved in this and indeed an apology to Dr. Rice for the way she has been treated.
