Febraury 20, 2012- PALM BEACH — David Koch has become the face of conservative America's obsession with weakening organized labor, and for that, he believes, there have been death threats - 100 credible threats last year alone, he says.
Journalists tend to describe the lanky MIT-trained chemical engineer and his brother Charles with the phrase "secretive oil billionaires."
They describe a clandestinely built political machine that disdains government regulation and taxes, obfuscates the science on global warming, and now pulls the strings of decision-makers at every level, from Florida Tea Party members to Wisconsin state senators - even U.S. Supreme Court justices.
"They make me sound like a bully," David Koch says when asked about journalists, looking a little baffled. "Do I look like a bully?"
On this night, Koch wants to talk about the battle against cancer, not unions.
