To safeguard other Americans. Our thoughts and prayers are with Glenn's father Bernard. His mother Barbara his brother Gregory his sister Kathleen. And there grieving families. Friends and colleagues. I was honored to know ambassador Chris Stephens. I want to thank. His parents and siblings who are here today. For sharing Chris with us and with our country. What a wonderful gift you gave us. Over his distinguished career in the foreign service Chris -- friends of the United States and far flung places. He made those people's hopes his own. During the revolution in Libya he risked his life to help protect the Libyan people from -- tyrant. And he gave his life. Helping them build. A better country. People love to work with press. And as he rose to the ranks they loved to work for Chris. He was known not only for his courage. But for his smile. Goofy but contagious. For his sense of fun and that California cool. In the days since the attack. So many Libyans including. The ambassador. From Libya to United States who is with us today. Have expressed their sorrow and solidarity. One young woman.

The president of the Palestinian Authority who worked closely with Chris when he served in Jerusalem. Sent me a letter remembering his. Energy and integrity. And deploring and I quote an act of ugly terror. Many others from across the Middle East and North Africa have offered similar sentiments. This has been -- difficult week. For the State Department. And for our country. We've seen the heavy assault on our post in Ben Ghazi. That took the lives of those brave men. We've seen rage and violence directed at American embassies over an awful. Internet video that we had nothing to do with. It is hard for the American people to make sense of that because it is senseless. And it is totally. Unacceptable. The people of Egypt. Libya. Yemen. And Tunisia. Did not trade that tyranny of a dictator. For that security of a -- Reasonable people and responsible. Leaders in these countries. Need to do everything they can't. To restore security. And hold accountable those behind. These violent acts. And we will under the president's leadership. Keep taking steps to protect our personnel around the world. There will be more difficult days ahead but it is important. That we don't lose sight of the fundamental fact. That America must keep leading the world. We owe it to those four men. To continue long hard work of diplomacy. I -- enormously proud. Of the men and women of the State Department. I'm proud of all those across our government. Civilian and military alike. Who represent. America abroad. They helped make the United States the greatest force. For peace progress and human dignity -- world has ever known. If the last few days teach us anything. Let it be -- be this. That this work and the men and women who risk their lives to do it. Are at the heart of what makes America great. And good. So we will wipe away our tears. Stiff and our spines. And face the future. Undaunted. And we will do it together. Protecting and helping one another. Just like Sean. Tyrone. The land. And Chris always did. May god bless them. And grant their families. Peace and solace. And may god continue to bless the United States of America. And now. Let me have the great honor. Of introducing someone who. Came to the State Department earlier this week. To grieve with us. He well understands. And values the work. That these men were doing for our country. The president of the United States. Scripture teaches us. Greater love hath no man than this. The man lay down his life. For his friends. -- ordered never shy and it. From invention. He believed that in his life he could make a difference. We're calling -- fulfilled as a navy seal.

And yes the idealist. -- fundamental American belief that we can leave this world a little better than before. That's who they -- And that's who. We are. We want to truly honor their memory. That's who we must always be. -- know that this awful loss. Terrible images of recent days the pictures we're -- again today. Have caused some to question this work. And there is no doubt these are difficult -- In moments such as -- So much anger. Violence. Even the most hopeful among us must wonder. But amid all the images of this week I also think of the Libyans who took to the streets with homemade signs. Expressing their -- -- to an American who believed in what. We could achieve together. I think the man and -- -- would decide in English. The message you want and all of us to hear. It said Chris Stephens was a friend to all Libyans. Chris Stevens was a front. That's the message these four patriots sent. That's the message that each of you. -- every day. Civilians military. Two people in every corner of the world. America is -- prime. That we care not just about our own country not just about our own interest. But about Bayer's. That even as voices of suspicion and mistrust seek to divide. Countries and cultures from one another the United States of America will never. Retreat from the world. We will never stop working for the dignity and freedom that every person deserves. Whatever -- creek. Whatever their faith. That's the essence of American leadership. That's the spirit of -- as part. From other nations. This was their work him in Gaza and and this is the work we will carry off. To view. And their families. And -- All Americans. -- -- Their sacrifice. Will never be forgotten. We will. Bring to justice. Those who took them from us. We will stand fast against violence. On our diplomatic missions. We will continue to do everything in our power to protect Americans serving overseas. Whether that means increasing security -- our diplomatic posts working with most countries which have an obligation to provide security. And making it clear that justice will come to those who harm Americans. Most of all. Even in our brief. We will be resolute. We are Americans. We hold our head -- Knowing that. Because of these patriots. Because of you. This country that we love will always shy and as a light unto the world. Greater love hath no man -- this. The man lay down his life. For his friends. Flagged they served -- are now carries them -- God bless the memory of these men who laid down their lives. For assault. May god watch over your families and all who loved them. May god bless. These United States of America. -- their families looking on President Obama speaking of the four Americans. Lost their lives saying today Glenn Tyrone Sean and Chris for our addiction. We'll stand together for the playing of the National Anthem. As we -- honor to the nation that these men loved him for which they died. Well. Let us -- Almighty god creator of those -- And lover. Of the human race. We commend to you are Brothers Chris and Sean. -- and entire run into your merciful -- receive them. Deliver them from all fair. Strengthen them in your presence. In give them your peace. I'm. The president the secretary of state. Hillary Clinton now approaching the families of the four Americans who were lost. The president saying moments ago to -- the families and colleagues their sacrifices will never be forgotten we will bring to justice. -- foreign affairs correspondent Martha Raddatz watching on the mean she's from her post in Washington this afternoon and Martha I was struck by the secretary of state almost with a message for. For the world saying the people in that part of the world did not trade tyranny of -- dictator. For the tyranny of a mom. Those were powerful words David when word I would say would sum up both of those remarks by President Obama and Secretary Clinton. Resolved. I'm also struck by these sad somber and powerful ceremonies. We've seen so many Americans come home. In the last decade thousands. Soldiers Marines. That this is selling usual for the State Department it's the first time in over thirty years and ambassador. Has been killed. By violence the State Department is not used to this these -- diplomats for Stevens wasn't armed they certainly have security. But for the most part they are going out to see people. Well I was reading a statement the mission statement of the State Department just now. Says shape and sustain a peaceful prosperous just and democratic world. And Foster conditions for stability and progress for the benefit of the American people and people everywhere that's how these people lived. That's how they died there is nothing more powerful than seeing these. Caskets with the flag on top of them might in on these flights before it is the most profound thing possible David. Profound especially Martha when you hear of the children left behind we heard the president and the secretary of State's because Tyrone -- children's wife Dorothy. Tyrone junior hunter and -- who -- Newly born. -- -- Smith his children Samantha and Nathan also remembered. At the service today. The secretary of state talking about. The California cool of ambassador Chris Stevens the career diplomat talking about his laugh -- smile personality calling it goofy. But contagious. And this week we've seen images from the state department's. -- and colleagues in mourning this week. They are indeed I know president Obama's visit to the State Department. Meant a great deal on that morning when they learned of ambassador Stephen's death. And those of the others. Walking around the State Department I know people. Our really truly in shock but I would say the same thing there is resolved there. They want to move forward they want to do the job that they have set out to do and as you -- the secretary and the president say. They will continue to do that job despite the violence we have seen. Across North Africa across the Middle East since then and some very powerful words about that anti Muslim movie. Secretary Clinton very strong words about that. Saying we had nothing to do within. And infecting -- our chief White House correspondent also with me this afternoon -- -- new calls for restraint from that new Islamist president of Egypt. Calling for calm and his country. That's right President Obama has been reaching out. Privately to the presidents -- Egypt Libya and Yemen asking them to urge calm in the streets and also urged them to provide protection. -- for the US diplomats who are there. Of course President Obama also sending submarines. To Yemen in Libya to help with that protection as well David. Some powerful and poignant moments in this hangar as you're looking -- at Andrews Air Force Base this afternoon our thanks to Jake Tapper. To Martha Raddatz will be joining -- later for a full report on world news. -- -- the hearse pulling out with the first of those caskets before Americans. Remember by both the president. And the secretary of state this afternoon. We want to return you now to your regular program will be following this all afternoon at abcnews.com.
