From his opening statement at press conference today (note, according to this transcript, the wierd Bob Dole-esque reference to himself as “Bill Frist”–he’s getting a bad case of majority leader disease):

We are here to urge our colleagues to allow the Bolton nomination to come back to the floor for an up-or-down vote. That’s the purpose of John McCain and Bill Frist today spending a few minutes with you. And I believe we can accomplish that. There’s a lot going on in terms of negotiations and letters and talking.
But now we’re at a point where the filibuster against Bolton — and, yes, I’ll call it a filibuster, because that’s where we are until we get it to an up-or-down vote on the floor of the United States Senate — is continuing.
Just looking back at the data and the statistics, it was over 200 days ago that the position of the U.N. ambassador came open with the resignation of our former colleague, Jack Danforth, who was then ambassador at the United Nations.
On March 7th, the nomination was announced. On March 17th, the nomination was sent to this body, the United States Senate. On April 11th, the Foreign Relations Committee held its hearing. On May 12th, sent to the floor, to our executive calendar. But on May 26th, through a cloture vote, this filibuster was begun.
At the same time, we have seen a whole sequence of events over the last 200 days. We’ve seen the Orange Revolution in Ukraine, the Cedar Revolution in Lebanon, the vote in Iraq, the vote in Palestine, the hope of opening the presidential elections in Egypt.
It’s been 200 days that this vacancy sign above our U.N. ambassador’s door in New York has been blinking. It is now a time to end that.
In addition, we’re seeing reports come out almost daily calling out for reform in the United Nations. We see the oil-for-food program. We’ve seen the problem with refugees. We’ve seen the human rights questionable commission there in terms of participation.
It is time to reform the U.N. It is time to bring Bolton to the floor for an up-or-down vote. We’re confident that he will be confirmed if we’re allowed to do so.
