(ABC News) - Facing a rocky confirmation process, Chuck Hagel today defended his record before his former Senate colleagues, including an openly impatient Sen. John McCain.
"I'm on the record on many issues, but no one individual vote, no one individual quote, no one individual statement defines me," Hagel said in his opening statement at his first confirmation hearing for secretary of defense.
"My overall worldview has never changed: that America has and must maintain the strongest military in the world, that we must lead in the international community to confront threats and challenges together," Hagel said.
A Vietnam veteran and former Republican senator from Nebraska who left office in 2009, Hagel, 66, is president Obama's nominee to replace Defense Secretary Leon Panetta. Despite his 12-year career in the Senate, Hagel faces opposition from many of his former Republican colleagues.
In a wide-ranging committee meeting that lasted all day on Thursday, Hagel faced questions on nuclear disarmament, the negative effects of potential automatic budget cuts known as "sequestration," and, most notably, Hagel's record on Middle East policy, including his stances on Israel, Iran, Hezbollah, and Hamas.
Hagel's exchanges with his former Republican colleagues took a bristly tone on a broad set of topics, as GOP senators repeatedly criticized his record and cut him off as he attempted to explain his stances
In the hearing's testiest exchange, McCain grilled Hagel on the former senator's opposition to the Iraq "surge," a stance that separated Hagel from most members of his party in 2007.
The Arizona senator championed the "surge" both as a senator and in his 2008 presidential campaign, while Hagel joined Democrats in vocally criticizing the strategy. McCain pressed Hagel at today's hearing to say whether he believes the surge was a mistake.
When Hagel declined to answer "yes" or "no," McCain told his former colleague, "I want to know if you were right or wrong. That's a direct question," repeatedly accusing Hagel of refusing to answer the question.
"You're on the wrong side of it, and your refusal to answer whether you were right or wrong on it is going to have an impact on my judgment on whether to vote for your confirmation," McCain concluded
