David Koch 

"He wore a navy suit, red-and-blue checkered tie, and a couple of fancy-looking convention passes sure to open doors that we reporters couldn't dream of entering." -- Mother Jones reporter 

Mr. Koch spent a few minutes taking questions from reporters. “We’re in this for the long haul,” Mr. Koch said, regardless of whether Mitt Romney wins or loses in November.

“It’s a free society,” Mr. Koch said. “People can invest what they want.” -- NYT
