WASHINGTON, May 24 - The Ohio Republican whose opposition to John R. Bolton as United Nations ambassador nearly stalled his nomination in committee took a new swipe at him today, circulating a letter urging colleagues to vote against Mr. Bolton when his name reaches the Senate floor, possibly this week.The letter from Senator George R. Voinovich was sent to all senators, but it was aimed particularly at fellow Republicans in a chamber in which the party holds a 55-44 majority (with one independent). In the letter, Mr. Voinovich said that while he had been "hesitant to push my views on my colleagues" during his years in the Senate, he felt "compelled to share my deep concerns" about Mr. Bolton's nomination. "In these dangerous times, we cannot afford to put at risk our nation's ability to successfully wage and win the war on terror with a controversial and ineffective ambassador to the United Nations," Mr. Voinovich wrote. He urged colleagues to "put aside our partisan agenda and let our consciences and our shared commitment to our nation's best interests guide us."
The White House remains strongly in favor of Mr. Bolton's nomination, and it is unusual for a Republican to break ranks so publicly by circulating a letter opposed to a Republican president's agenda. A copy of Mr. Voinovich's letter, dated May 23 but not circulated until Tuesday, was provided by a Senate Democratic aide opposed to Mr. Bolton.
