Former secretary of state Hillary Rodham Clinton got her budding presidential campaign's first targeted question about the deadly 2012 Benghazi terror attacks on Tuesday night, and her answer was the sound of one hand clapping. The bash-the-rich candidate flew first class from Boston to Washington, D.C. after wrapping up a two-day New Hampshire campaign trip. Daily Mail Online was on the flight. 'Mrs. Clinton, when are you going to start talking to the press about Benghazi?' Daily Mail Online asked her in the Washington Reagan National Airport terminal. 'Did you make mistakes?' The usually garrulous and broad-smiling Clinton stared straight ahead, continued walking alongside her Secret Service and local police escorts, and said nothing. SCROLL DOWN FOR VIDEO . NO COMMENT: Hillary stared ahead and walked wordlessly Tuesday, refusing to acknowledge her first campaign-trail question about the deadly Benghazi terror attacks in 2012 . DEADLY: The September 11, 2012 Benghazi terror attacks killed four Americans including the US ambassador to Libya . WRONG: Both President Barack Obama and then-Secretary of State Clinton incorrectly blamed the Benghazi attacks on protests sparked by a YouTube video mocking Islam's prophet Muhammad. The two are shown at a ceremony held to receive the remains of the four Americans who were killed at the scene . Moments earlier, she answered a question about why her taxpayer-funded security detail had sped at 80 MPH past exits for the smaller Manchester, New Hampshire airport, and trekked all the way to Boston for a flight with first class seats. 'You know, I don't make the travel arrangements. I don't,' Clinton said. The Islamist terror group Ansar al-Shariah's military-style Benghazi attacks will likely be a thorn in Clinton's side throughout the 2016 presidential campaign season. The group laid waste to a State Department facility while she was America's top diplomat. A special congressional committee chaired by South Carolina Republican Rep. Trey Gowdy, a former criminal prosecutor, has a mandate to investigate the episode through January 2017, making it unlikely that Clinton will be able to put the issue behind her. TROUBLE AHEAD: New Hampshire resident Brian Blackden included 'Benghazi blood' Tuesday on a sign listing reasons 'Hillary is a liar,' near the site of a Clinton appearance at the New Hampshire Technical Institute . On Sunday during a series of 50 brief interviews with Dartmouth College students in Hanover, New Hampshire, 22 of them made references to Bengahzi when asked about Clinton's chances of becoming president. Many of them, like freshman Cameron Poole, weren't old enough to drive when it happened. 'I think there was blood on her hands,' Poole told Daily Mail Online. He said he believes Clinton's performance before, during and after should disqualify her from holding higher office. 'I definitely do,' he said. 'It shows how she acts under pressure.' NOT FORGOTTEN: U.S. Ambassader the Libya Chris Stevens was the first to die in Benghazi, and was seen by Libyans as a moderate – angering anti-American hardliners from radical Islamist groups . CASUALTIES: US Foreign Service Information Management Officer Sean Smith (left), US Navy SEAL Glen Doherty (center) and US Nacy SEAL Tyrone Woods (right) perished in the Ansar al-Shariah attacks in Benghazi . Four Americans lost their lives in the September 11, 2012 terror attacks, including U.S. Ambassador to Libya Christopher Stevens, the first American ambassador killed while on duty since 1979. U.S. Foreign Service Information Management Officer Sean Smith also perished in the initial barrage of mortars and automatic weapons fire. Hours later, a second wave of attacks hit a CIA annex compound nearby, killing CIA contract soldiers Tyrone Woods and Glen Doherty, both U.S. Navy SEALs. The four men came home in flag-draped caskets. Congressional Republicans want answers about Clinton's involvement in what they see as a potential cover-up of facts surrounding how the attacks unfolded and why – and how the Obama administration explained it afterward, just weeks before an election. Part of the swirling controversy involves a home-brew email server that Clinton exclusively used for her official electronic communications while she was secretary of state. Clinton never used an official 'state-dot-gov' email address, but told reporters on March 10 that she had given the State Department copes of 'official' emails – and acknowledged deciding herself which ones qualified. She deleted the rest, some 32,000 messages in all. Clinton's attorney has refused to hand over the server to congressional investigators. Gowdy, the Benghazi committee chairman, wants a neutral third-party to examine it and determine if Benghazi-related emails can be recovered. His committee said Wednesday that its report on the Benghazi attacks won't likely be finished until 2016, putting its release squarely in the middle of the presidential campaign's most hotly contested months. But the committee said in a statement that 'Secretary Clinton’s decision to seek the presidency of the United States does not and will not impact the work of the committee.' Clinton's State Department infamously declined to provide her Benghazi outpost with the beefed-up security presence its station chief requested in the weeks preceding the deadly Ansar al-Shariah attacks. She claimed later that she never saw the requests, insisting that such routine diplomatic cables would never have made it to her desk, even if they were addressed to her. FIRST CLASS: Hillary (seated at the front, right) traveled in luxury from Boston to Washington, seated next to chief of staff Huma Abedin, after am 80 MPH Secret Service dash to Logan International Airport . FAREWELL: Hillary Clinton waved at the end of her final campaign stop in New Hampshire on Tuesday, before hitting the road to Boston for the same Washington-bound flight that Daily Mail Online flew on . In the days following the attacks, Clinton said publicly that it was the result of a spontaneous protest over a YouTube video made by an American – a film that insulted the Islamic prophet Muhammad. Such protests were seen in other Muslim countries, but U.S. intelligence determined in real-time that the Benghazi attacks were well-organized and easily traced back to an Islamist terror network. Months later, following a concussion that delayed her congressional testimony about Benghazi, she testified in a U.S. Senate Foreign Relations Committee hearing. Just days earlier, lawmakers disclosed that a top U.S. diplomat told them 'everyone' at the American diplomatic outpost in Benghazi knew 'from the beginning' that they were in the middle of a terrorist attack. 'The fact is we had four dead Americans,' Clinton told the senators. 'Was it because of a protest or was it because of guys out for a walk one night who decided that they’d they go kill some Americans?' 'What difference at this point does it make?'
