"I enjoyed meeting David Koch in 2013. David was was so engaging and interesting. If all successful men in our country felt the responsibility to their country that David felt, the benefits to all would be immeasurable. By example, David lived the American Dream of opportunity and limitless horizons. During his lifetime he (and his brother Charles should also be credited) greatly contributed to medical and scientific research, the cultural arts, and political action that ensures the continuation of the great freedoms and opportunities only this country offers. He was a great man."
