Sen. Chuck Schumer, D-N.Y., thanked the Koch brothers‘ political action committee for donating to his re-election campaign back when he was running for office, not trying to protect a Senate majority that he hopes to lead by attacking the Kansas billionaires on a regular basis.

“Thank you so much for the generous KOCHPAC contribution to my 2010 campaign for reelection to the United States Senate,” Schumer wrote in a 2009 letter published by Powerline. “Your early financial help keeps me strong in my campaign. In return, I promise to continue working as hard as I can to help our nation reach its maximum potential.”
