And at this hour, a look inside the rotunda, where the former president now lies in state, as americans and lawmakers from both parties line up to pay their respects to the last president of the greatest generation.

The casket was then carried up the steps to the rotunda. The emotions of a son and former president , you could see it as he watched his father return to washington. Inside, the casket was placed on the lincoln catafalque. The same stand that once held president abraham lincolns coffin. It was a long and remarkable journey for president bush, the boy from milton, massachusetts, born in 1924. The son of a banker and a senator. He would later meet the love of his life, barbara pierce, at a christmas dance. He was the first boy she would kiss. The following year, george enlisted in the navy on his 18th birthday. While overseas, he would write to barbara, his darling bar. Two years in, on his 50th mission, he was shot down over the pacific. He was rescued and he made it home to barbara. They would have six children and among them, a little girl named robin, who died of leukemia at 3. It was a loss that broke both of them. He was very close. I was very close to her. She adored him. What was it that pulled you back up on your feet afterwards . He was very strong then. He was wonderful. From the oil business to politics, he was a congressman, an ambassador, a cia director, and the loyal Vice President to ronald reagan. He would then get his own chance. I want a kinder and gentler nation. As president , guiding the country through the end of the cold war and driving Saddam Hussein out of kuwait. But with the economy at home being tested, he would lose reelection to bill clinton, describing the loss to diane sawyer. Just had a great feeling of letting down a lot of people. A lot of people that worked for me. You have this ghastly feeling you let them down. And then you get over it and you go on with your life. But he would leave a letter in the oval office for bill clinton, writing, i wish your family well. Your success is now our countrys success. Im rooting hard for you. He would later build an unlikely friendship with bill clinton, and they would raise money for the victims of the tsunami and here at home after katrina. President bush and his wife, barbara, were married 73 years, the longest of any president and first lady. And we would learn he held her hand until the end. He lost her just eight months ago. At her funeral, the clintons, the obamas and first lady melania trump. And barbara bush revealing along the way how she wanted her husband to be remembered. He is the most decent, honorable, wonderful nobodys ever been as lucky as ive been. I want people to remember him as courageous. I want them to remember him as he is. It was less than a year ago he sat before his wife. There was sadness, but not fear, as he once told diane. I do think that that you go to heaven, there is a heaven, and i dont fear it, though. When i was a little guy, id fear death, id be worried about it, be scared. Not anymore. Not fearing death in the end. And what he said when he was asked who he wanted to see in heaven. Thats coming up a bit later here. And one more pointed image tonight. President bushs service dog, you saw sully in front of the coffin today. The labrador, we learned tonight, he boarded that flight to washington, as well.

I want to bring in abcs chief White House Correspondent jonathan karl, live tonight, and jon, we know there had been tension when donald trump was running for office, what was said about the bushes, but jon, this really is a moment of unity here in washington. Reporter it sure is, david. And in fact, this will be the first time that we will see all of the living president s together since the inauguration of donald trump. And it is a moment of unity that is really befitting of george h. W. Bush. This was somebody known for striking up genuine friendships with people who had been bitter rivals, and in the case of donald trump, the resentment went both ways. Of course, trump was as harsh a critic as there was of the bush family, and george h. W. Bush so resented trump that he actually crossed party lines and voted for hillary clinton. But when it came time for trump to become president , at the inauguration, the former president bush, the elder bush, wrote him a letter, saying, i want you to know, i wish you the very best as you begin this incredible journey of leading our great country. So, yes, david, a moment of unity, as the country pays tribute to george h. W. Bush. All right, jon karl across town at the white house tonight. Jon, thank you.
