This morning, The New York Times' Steven R. Weisman reports on a second allegation that Bush's nominee to be U.N. Ambassador, John Bolton, bullied low-level bureaucrats, a potential sticking point in his case for approval by the Senate. Today, a second Republican Senator on the Foreign Relations Committee intimated that he might not vote for Bolton. The AP's Siobhan McDonough has the story:

A top Senate Republican raised the possibility Sunday that he might vote against President Bush's nominee to be U.S. ambassador to the United Nations if more accusations surface about John Bolton's alleged harassment of analysts who disagreed with his views.

With a Senate Foreign Relations Committee vote expected Tuesday, Sen. Chuck Hagel of Nebraska was asked whether he would endorse Bolton.

"At this point, I will ... but I have been troubled with more and more allegations, revelations, coming about his style, his method of operation," said Hagel, the committee's No. 2 Republican.

"We need a uniter," he told CNN's "Late Edition." "We need a builder. We need someone who will reach out to our friends and our allies at the United Nations."

Bolton's nomination might not be dead, but it's certainly on life-support at this juncture. Should either Hagel or Linc Chafee (R-RI) vote against Bolton in this weeks vote, Bush's nominee will be defeated, a surprising blow for the administration as it tries to strong arm Congress.
