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.
