Washington (CNN) -- The State Department's former point man on security in Libya told a congressional hearing Wednesday that his superiors worked against him as he tried to get more help for the U.S. diplomatic mission in Benghazi in the months before it was overrun in a deadly terror attack. Eric Nordstrom, the one-time regional security officer, told the House Oversight Committee that he had a disheartening conversation with the regional director of the agency's Bureau of Near Eastern Affairs when he requested additional manpower for the facility. "I said, 'Jim, you know what makes it most frustrating about this assignment? It's not the hardships. It's not the gunfire. It's not the threats. It's dealing and fighting against the people, programs, and personnel who are supposed to be supporting me," Nordstrom said. He also told the State Department officer, "'For me, the Taliban is on the inside of the building." That bombshell ended a contentious hearing during which two State Department officials defended the Obama administration's handling of the September 11 attack that killed Ambassador Christopher Stevens and three other Americans. What we know about the Libya attack . Benghazi has become a flashpoint in the presidential campaign with Republican Mitt Romney saying the attack illustrates that President Barack Obama's policies have made America less influential and more vulnerable around the world. Under Secretary of State for Management Patrick Kennedy responded to suggestions the State Department was responsible for a lack of preparedness. "We regularly assess risk and resource allocation, a process involving the considered judgments of experienced professionals on the ground and in Washington, using the best available information," Kennedy said. The assault on the U.S. compound was "an unprecedented attack by dozens of heavily armed men," Kennedy said. His colleague, Deputy Assistant Secretary of State for International Programs Charlene Lamb, added that the State Department "had the correct number of assets in Benghazi at the time," drawing a sharp rebuke from committee Chairman Rep. Darrell Issa, R-California. "To start off by saying you had the correct number, and our ambassador and three other individuals are dead, and people are in the hospital recovering because it only took moments to breach that facility somehow doesn't seem to ring true to the American people," Issa said. Republican committee members and the State Department officials went back and forth about the appropriate number of people needed to provide security at the vulnerable Benghazi location. Various communications dating back nearly a year asked for anywhere from three to five diplomatic security special agents. As the four-hour hearing drew to a close, Nordstrom divulged he had verbally asked for significantly more help -- 12 agents -- but the officer from the Bureau of Near Eastern Affairs had rebuffed his request. "His response to that was, 'You're asking for the sun, moon, and the stars,'" Nordstrom said. That attitude made the Benghazi incident predictable, according to Nordstrom, who left Libya in July and continues to work at the State Department for diplomatic security. "For me and my staff, it was abundantly clear that we were not going to get resources until the aftermath of an incident. And the question that we were to ask again is, 'How thin does the ice have to get before someone falls through?'" Five special agents were in Benghazi at the time of the attack, Issa said. Two of them only happened to be there only because they had traveled with Stevens from Tripoli, Lamb said. "The post had agreed that three was a sufficient number to have on the ground." Lamb said. But Lt. Col. Andrew Wood, a Utah National Guardsman who was a site security commander in Libya from February through August, testified that the regional security officer -- it was unclear if he was talking about Nordstrom -- tried to obtain additional personnel, but "was never able to attain the numbers he felt comfortable with." "The security in Benghazi was a struggle and remained a struggle throughout my time there," Wood said. "Diplomatic security remained weak. In April, there was only one U.S. diplomatic security agent there." U.S. official sought more security for Benghazi post . State Department officials also responded to allegations by Republicans that the Obama administration intentionally misled the public about the cause of the attack. Critics accuse the administration of trying to cover up or play down the attack through initial statements that described it as a spontaneous act stemming from protests over an anti-Muslim film rather than a planned terrorist assault. "We have always made clear that we are giving the best information we have at the time. And that information has evolved," Kennedy said, citing remarks by U.N. Ambassador Susan Rice on September 16 that critics alleged were deceptive. "For example, if any administration official, including any career official, were on television on Sunday, September 16, they would have said what Ambassador Rice said. The information she had at that point from the intelligence community is the same that I had at that point. Clearly, we know more about today than what we did." While congressmen from both parties agreed that security at overseas U.S. diplomatic posts is crucial, and they expressed hope for a bipartisan solution, several times during the hearing the dialogue devolved into rancorous comments back and forth. The assault in Benghazi occurred 11 years to the day after the September 11, 2001, attacks on New York's World Trade Center and the Pentagon. Kennedy said the fullest picture of proper security and procedures will not be fully clear until a review board appointed by Secretary of State Hillary Clinton and including former Joint Chiefs Chairman Adm. Michael Mullen is completed. State Department officials: Benghazi attack 'unprecedented' Democrats had accused Issa of planning a partisan, election-year hearing, a similar allegation leveled against the panel for its past investigations of the botched "Fast and Furious" gun-running program and the failed Solyndra clean energy company that received government loan guarantees. On Tuesday, two senior State Department officials provided reporters with the most detailed explanation yet of the attack in Benghazi, saying on a conference call that there was no prior indication such an assault was imminent. The officials, who briefed reporters on condition of not being identified by name, said there was "nothing unusual" throughout the day of the attack. What Obama administration has said about Libya attack . Stevens held an evening meeting with a Turkish diplomat and then retired to his room in one of the compound's buildings at 9 p.m., according to the officials. The first sign of a problem came 40 minutes later, when diplomatic security agents heard loud talking outside the compound, along with gunfire and explosions. Asked whether the attack was a spontaneous assault taking advantage of a demonstration, as originally asserted by Obama administration officials, one senior official said, "That was not our conclusion." The two senior officials offered riveting detail of the attack by what one of them described as "dozens of armed men" who marauded from building to building and later fired mortars on a U.S. annex less than a mile away. In the havoc at the four-building compound, Stevens and two of his security personnel took refuge in a fortified room that the attackers were able to penetrate, one official said. The attackers doused the building with diesel fuel and set it ablaze and the three men decided to leave the safe haven and move to a bathroom to be able to breathe, according to the official. Stevens became separated from the security personnel in the chaos and smoke, and eventually turned up at a Benghazi hospital, where he was declared dead. Romney knew ex-SEAL slain in Benghazi .

Oceanside, New York (CNN) -- Deployed to a volatile outpost in southern Afghanistan where U.S. Marines routinely face a mix of skirmishes and hidden explosives, Greg Buckley Jr. sensed that an attack was imminent. And he knew that it would come from within. The 21-year-old Marine was posted to Garmsir in Helmand Province, where he was training local security forces as part of NATO's planned withdrawal in 2014. It was during a static-filled phone call to his father over the summer that the Long Island native mentioned a run-in he had with an Afghan trainee while on guard duty. NATO releases details of brazen raid on base in Afghanistan . The encounter was the first in which the Buckley family's eldest son seemed to sense something was wrong, according to what he told his family in phone conversations and a letter. "The guy turned around and said to Greg, 'We don't want you here. We don't need you here,'" his dad said. "Greg turned around again and said, 'Why would you say that?'" according to Greg Buckley Sr. But the trainee apparently wouldn't relent, repeating the phrases for hours over the course of a night in which the young Marine was on guard watch. "Greg said, 'I thought I was going to lose my mind,'" his father said. "Pitch black out, and all he kept saying over and over again is, 'We don't want you. We don't need you. We don't want you.'" "It was just tormenting for him." The two men then finally confronted each other, yelling until a group of officers separated them, he told his father. "One of his superiors came over and had Greg apologize to the guy," said the elder Buckley. The 21-year-old agreed and extended his hand, but the man refused. About a month later, Greg phoned his father again. "He told me if I have to stay here until November... I'm not going to come home." Greg also asked his father to prepare to tell his mother and his two younger brothers that he'd be killed. "I don't understand," his father said. "Out in the field?' "No, in our base," Greg replied. 4 NATO troops killed in 'insider' attack in Afghanistan . On August 10, 2012, Greg Buckley Jr. was gunned down by the very forces he had been training, just days after learning that he was to head home early. "It was only two days he had left there in Afghanistan," his father told CNN. The phenomenon is known as "green-on-blue," due to a color-coding system used by NATO. It has become disturbingly more frequent in Afghanistan, with more than 50 NATO troops killed this year by local forces, the first time that's happened in a single year in the U.S.-led war. Last year, 35 people died in such insider attacks, and even less the year before, according to NATO figures. The killings have prompted suspensions of training new recruits while eroding the trust between NATO and its Afghan allies. The gunman involved in Greg's death attacked from inside his outpost and killed two other fellow Marines, his dad said. But Greg Sr. said his son had informed his superior officers that "one day they are going turn around and turn those weapons on us." CNN cannot independently confirm that Greg informed superior officers. Calls and emails to NATO's International Security Assistance Force in Afghanistan were not immediately returned. More than a decade after the war began, the Buckley family is now struggling to cope with the loss of its eldest son. More than 2,000 other U.S. service members have been killed in Operation Enduring Freedom. "It's not really day-by-day," said Greg's mother, Marina Buckley. "It's more minute-by-minute." Back in Oceanside, the Buckley family on Friday attended the town's first home football game, where their fallen son had intended to watch his youngest brother play varsity for the first time. "Greg was supposed to be home for this game," said Justin, 17, who wore the number 30 on his back, Greg's old basketball number. "I would tell him I love him and I miss him." The senior running back, who donned a camouflage jersey along with his team, broke to the outside on Friday for a 25-yard score that helped cement the Sailors' improbable second-half comeback against top-ranked East Meadow. After crossing into the end zone, Justin raised his hand to salute -- honoring his fallen brother. NATO admits killing civilians in Afghan strike .

(CNN) -- Rafael Nadal will miss the U.S. Open after the reigning champion couldn't recover in time from a right wrist injury. The world No. 2 injured his wrist after Wimbledon and pulled out of the recent Masters events in Toronto and Cincinnati. Due to make an announcement over the weekend about his participation at Flushing Meadows, that decision was pushed back to Monday and the Spaniard's fans were ultimately left disappointed with the outcome. "I am very sorry to announce I won't be able to play at this year's U.S. Open," the 28-year-old announced on his Facebook page. "I am sure you understand that it is a very tough moment for me since it is a tournament I love and where I have great memories from fans, the night matches, so many things. "(There is) not much more I can do right now, other than accept the situation and, as always in my case, work hard in order to be able to compete at the highest level once I am back." It's not the first time Nadal won't be able to defend a grand slam title. He also skipped Wimbledon in 2009, the year after his memorable triumph over Roger Federer at the All England Club, when his knees were the issue. Injuries have been an ever present in the 14-time grand slam winner's career, with those knees the biggest culprit. But a hamstring injury hindered Nadal at the 2011 Australian Open -- when he was on the verge of capturing a fourth consecutive grand slam titles -- and in Melbourne seven months ago, back pain meant he was unable to perform at his best in the finale versus Stan Wawrinka. His absence means Federer will be bumped up to No. 2 in the seedings, only behind Novak Djokovic. Federer has been the hottest player this summer, reaching the final in Toronto and winning Cincinnati, and without his nemesis at the U.S. Open, the Swiss' chances of landing a record-extending 18th major have now improved. Nadal is the highest profile casualty of the U.S. Open, though 2009 champion Juan Martin del Potro also withdrew with a wrist injury. The tournament begins next Monday.
