My job to say when I think it's true it's my job to say what I think will work it's my job to Carla Farley post. Whether it straightens and Matt I don't know I don't know whether it's gonna have an effect on them but there's no other way fair and honest critic. To be. That was Charles Krauthammer a one of the most powerful and brilliant minds and conservative media of all time. His son Daniel is sharing an intimate portrait of his father's life and legacy and battle with cancer. In a new book called the point of at all please welcome my friend in a hammer. It's incredible dot but the country is mourning the loss President Bush we just wanted to know what you think your father would've sat at his Pasadena secret a photo. A band together actually. If there. Who. Yeah I had you know it's. It hits me hard seeing I'm sure as you feel too. For the bush family just knowing how they feel right now and when I heard the news about. President Bush is passing an excellent back. I wonder what my dad would think and read some of the cons he had written about President Bush and I found one. That he wrote just after the election 92. When President Bush and lost and as a time when the comedian was piling on criticizing and left and right. And he said something and I think cold so true today. I was amazed that it was written over twenty years ago but he said. You know President Bush may have lost but that's not history's verdict this wasn't a failed presidency it was a completed presidency. But he rose to the great challenges of the time of ending the cold war on our terms of meeting Saddam Hussein. And he finished his job for history essentially had my dad at a very deep sense of history and compared him to Churchill and Truman and other presidents did great things but then essentially they're turning history was done. This is why I would race home Ed free night. At 6 PM to watch your dad on special report on fox because he really helped shape the modern conservative movement but. He was able to disagree so respectfully and he would. At times he would be very critical of president trump for example and when it's not popular many places and he would go places that many conservatives would never go. We read about courage come from. I think. It was courage for sure but not for its own sake I think he felt a real duty. An obligation to be honest. That in the inner you clip you played just earlier on an interview. He's saying. You know look I chose this life to to write about politics to be a critic. And if I'm not gonna say what I really think what's the point of this and he and actually had an earlier period as a doctor was a psychiatrist. And he chose to leave that a professional Reid knew he was helping people having a real impact. And so he said you know I'm will leave that to do this which I care about which I've passion for I better be honest and say what I think Carlson betraying everything I've done. And he sticks it true that to the area and yeah he was an honest and I like yeah. Because. You don't. I always feel like. If you couldn't give somebody the respect of saying you know what. I don't agree but I like how you do act. I just never. Thought infamous faltering ever so I was a huge fan of his we didn't agree on a lot of stuff went you know he had. He had that thing. That you want and people who are telling you what's going not. A sense of what the country needed not the party but what the country needed to know and so.
