WASHINGTON — In one of her final appearances as secretary of state, Hillary Rodham Clinton on Wednesday vigorously defended her handling of the Sept. 11 attack on the US diplomatic compound in Benghazi, Libya, which killed four Americans and prompted a scathing review of State Department procedures.
“As I have said many times, I take responsibility, and nobody is more committed to getting this right,’’ she said, reading a statement during a day of testimony before Senate and House committees. ‘‘I am determined to leave the State Department and our country safer, stronger, and more secure.’’
But Clinton, whose appearance before Congress had been postponed since December because of illness, quickly departed from the script. She jousted with Republicans lawmakers over who deserved blame for the security problems at the compound and choked up as she described being at Joint Base Andrews, outside Washington, when the bodies of the Americans killed in the assault arrived from Libya.
“I stood next to President Obama as the Marines carried those flag-draped caskets off the plane at Andrews,’’ she said. ‘‘I put my arms around the mothers and fathers, sisters and brothers, sons and daughters.’’
The continuing controversy over the attack, which resulted in the deaths of Ambassador J. Christopher Stevens and three other Americans, has cast a cloud over Clinton’s final months at the State Department. It also has enormous political implications for the former New York senator, who is already regarded as the front-runner for the 2016 Democratic presidential nomination if she chooses to run. It was the first time she had faced extensive questioning about her role in the episode.
In essence, Clinton’s approach was to accept the responsibility for security lapses in Benghazi but not the blame.
“I feel responsible for the nearly 70,000 people who work for the State Department,’’ Clinton told the Senate Foreign Relations Committee in the morning. ‘‘But the specific security requests pertaining to Benghazi, you know, were handled by the security professionals in the department. I didn’t see those requests. They didn’t come to me. I didn’t approve them. I didn’t deny them.’’
When the question of her role was taken up again in the afternoon hearing by Representative Ed Royce, Republican of California, who chairs the House Foreign Affairs Committee, Clinton acknowledged that she had been briefed on a series of events that indicated that security in Benghazi was deteriorating in the months before the attack. They included the placement of a bomb at the outer wall of the compound in June and an ambush that month on the British ambassador.
But she said she had gone along with a recommendation from subordinates that the Benghazi post be kept open and assumed that they would take the necessary steps to protect it.
One of the sharpest exchanges of the day came when Clinton responded to questions from Senator Ron Johnson, Republican of Wisconsin, by saying there was too much focus on how the Benghazi attack had been characterized in its early hours and not enough on how to prevent a recurrence. Republicans have repeatedly charged that Obama administration officials deliberately played down the attack, focusing much of their criticism on Susan E. Rice, the ambassador to the United Nations and once Obama’s choice to replace Clinton.
“Was it because of a protest, or was it because of guys out for a walk one night who decided they'd go kill some Americans? What difference, at this point, does it make?’’ Clinton said, her voice rising. ‘‘It is our job to figure out what happened and do everything we can to prevent it from ever happening again, senator.’’
Senator John McCain, Republican of Arizona, began his questions by saying, ‘‘It’s wonderful to see you in good health and as combative as ever,’’ and then proceeded to complain that his former Senate colleague had failed to answer lingering questions.
McCain asserted that the Obama administration’s aversion to nation-building had precluded it from providing the kind of training and assistance that would have helped the fledgling Libyan government in Tripoli confront growing security threats from militants.
“We did not give them the kind of assistance that would have been necessary to help dismantle these militias that still, to this day, remain a challenge to democracy in Libya,’’ he said.
Clinton responded that Congress had delayed aid to Libya and said she would provide a list of steps that had been taken to train and equip Libyan forces.
A persistent line of questioning by Republican lawmakers concerns the initial comments from Rice that the attack might have resulted from a protest, over an anti-Islamic video, that spun out of control.
Clinton defended Rice even as she appeared to distance herself from Rice’s comments.
‘'I told the American people that heavily armed militants assaulted our compound, and I vowed to bring them to justice,’’ Clinton said.
The Senate Foreign Relations Committee is still led by Senator John Kerry, the Massachusetts Democrat whose confirmation hearing as secretary of state is Thursday. Kerry did not lead the Wednesday hearing to avoid the perception of a conflict of interest.
