WASHINGTON — Chuck Hagel, President Obama’s nominee to be secretary of defense, came under sharp and sometimes angry questioning Thursday on a wide range of issues from fellow Republicans at his Senate confirmation hearing, including from his old friend, Senator John McCain, the Arizona Republican who is still smoldering about their break over the Iraq war.
Mr. Hagel, 66, a former senator from Nebraska and a decorated Vietnam veteran who would be the first former enlisted soldier to be secretary of defense, often seemed tentative in his responses to the barrage from fellow Republicans on the Senate Armed Services Committee, who showed him little deference and frequently cut him off.
One of the most hostile questioners was Senator Lindsey Graham of South Carolina, who told Mr. Hagel to “give me an example of where we’ve been intimidated by the Israel-Jewish lobby to do something dumb.'’ Mr. Hagel, who in 2006 said the “Jewish lobby” intimidates Congress, could not.
From Mr. Hagel's home state, Senator Deb Fischer told Mr. Hagel that he held "extreme views" that were "far to the left of this administration.'' Senator Ted Cruz, Republican of Texas, surprised the hearing with excerpts on a giant video screen from an interview Mr. Hagel gave to Al Jazeera in 2009. Although it was difficult to hear the short clips he provided, Mr. Cruz asserted that they showed Mr. Hagel agreeing with a caller who suggested that Israel had committed war crimes.
“Do you think the nation of Israel has committed war crimes?'’ Mr. Cruz demanded.
“No, I do not, Senator,'’ Mr. Hagel replied.
But his exchange with Mr. McCain was the most notable, given that the two former Vietnam veterans were close friends when they served in the Senate until Mr. Hagel’s views on the Iraq War caused a split. In 2008, Mr. Hagel did not endorse Mr. McCain for president and traveled with Mr. Obama, then a senator from Illinois, to Iraq and Afghanistan.
Mr. Hagel dodged a direct answer as Mr. McCain asked him repeatedly if history would judge whether Mr. Hagel was right or wrong in opposing the surge in American armed forces when he was in the Senate. The escalation, along with other major factors, is credited in helping to quell the violence in Iraq at the time. When Mr. Hagel said he wanted to explain, Mr. McCain bore in.
“Are you going to answer the question, Senator Hagel — the question is whether you were right or wrong?” Mr. McCain said.
“I’m not going to give you a yes or no answer,” Mr. Hagel replied.
Mr. McCain did not let up.
"I think history has already made a judgment about the surge, sir, and you’re on the wrong side of it,” Mr. McCain said, then seemed to threaten that he would not vote for Mr. Hagel if he did not answer the question.
It took the next questioner, Senator Bill Nelson, Democrat of Florida, to draw Mr. Hagel out on the subject. “I did question the surge,” Mr. Hagel said. “I always asked the question, is this going to be worth the sacrifice?” He said 1,200 American men and women lost their lives in the surge. “I’m not certain it was required,” Mr. Hagel said. “Now, it doesn’t mean I was right.”
Despite the theatrics, it was unclear how the committee would vote on Mr. Hagel’s nomination. He needs a majority of the 26-member panel, which includes 14 Democrats, almost all of whom are likely to support his nomination. And there remained a possibility that perhaps one or two Republicans would join them. If Mr. Hagel advances out of the committee, he would have an easier time when the entire Senate votes on his confirmation.
The onslaught by Republicans, however, began even before Mr. Hagel made his opening statement.
The ranking Republican on the committee, Senator James M. Inhofe of Oklahoma, told Mr. Hagel that he would not vote for him because of his position of “appeasing” America’s adversaries.
