G.O.P. Aides Add Voices to Resistance Over Nominee
By DAVID D. KIRKPATRICK
As the White House seeks to rally senators behind the Supreme Court nomination of Harriet E. Miers, lawyers for the Republican senators on the Judiciary Committee are expressing dissatisfaction with the choice and pushing back against her, aides to 6 of the 10 Republican committee members said yesterday.
“Everybody is hoping that something will happen on Miers, either that the president would withdraw her or she would realize she is not up to it and pull out while she has some dignity intact,” a lawyer to a Republican committee member said.
All the Republican staff members insisted on anonymity for fear of retaliation from their supervisors and from the Senate leaders.
At two stormy meetings on Friday – the first a planning meeting of the chief counsels to Republican committee members and the second a Republican staff meeting with Ed Gillespie, the former Republican Party chairman who is helping to lobby for the nomination – committee lawyers were unanimous in their dismay over Ms. Miers’s qualifications and conservative credentials, several attendees said.
Many lawyers were critical or hostile, these people said, although Michael E. O’Neill, chief counsel to the committee chairman, Senator Arlen Specter of Pennsylvania, tried to remain relatively neutral. Mr. O’Neill could not be reached for comment.
“You could say there is pretty much uniform disappointment with the nomination at the staff level,” another Republican on the committee staff said. “It is clear there is quite a bit of skepticism, and even some flashes of hostility.”
Another Republican aide close to the committee said, “I don’t know a staffer who approves of this nomination, anywhere. Most of it is outright hostility throughout the Judiciary Committee staff.”
In an interview on Tuesday, Mr. Specter emphasized that the senators would make their own decisions.
“I think those staffers, like anybody else, have a right to their opinions and to express them,” he said. “Senators will make independent judgments. You have some pretty strong staffers on the committee, but you have got some stronger senators.”
