READ about Piers Morgan's long career in journalism here.
On Thursday night, well-known columnist and editor Arianna Huffington visited "Piers Morgan Tonight" to offer her candid thoughts on the passing of Andrew Breitbart.
Having know the conservative blogger – and his family – for more than a decade, Huffington's mind was on those he has left behind:
"All my thoughts, all day, since I heard the tragic news around nine o'clock this morning have been around Susie, his amazing wife, who has always been as peaceful and calm, as Andrew has been fiery every time I have spent any moments with him."
Currently the editor-in-chief of the "Huffington Post," the author worked with Breitbart at multiple points during their respective careers, and remembered his intense passion and focus:
"He would work late into the night. He would get up early. He would sleep with his laptop," recalled Huffington. "I remember that when we started working together, I was working out of my home in Los Angeles, and my children were five and seven, and we would all joke – my mother lived with me too – just it's hard to get Andrew out of the house, because he loved his work, whatever he was doing."
Watch the clips, and listen to the interviews, as Huffington reflects on a man who "was full of passion, exuberance, fearlessness," and "obsessed with facts."
