Koch brothers group toughens advertising attacks against Jeff Merkley
A group tied to the Koch brothers is releasing a tough new ad that more directly urges Oregon voters to oust Sen. Jeff Merkley, D-Ore. Previous TV commercials from Freedom Partners -- a group tied to the conservative political network formed by industrialists Charles and David Koch -- have been pitched as issue ads that end by urging voters to call Merkley and tell him to do something.
