RNC warns donors to steer clear of Kochs

The Republican National Committee is sending a warning shot to major GOP donors not to play ball with the powerful Koch political network, escalating a fight between President Donald Trump’s allies and the Kochs. The move follows a weekend retreat in Colorado at which Koch network officials criticized the Trump administration, hinted they would work with Democrats, and announced they would not help a Republican candidate in a key 2018 Senate race. The Kochs have long expressed unease with Trump, choosing to sit out the 2016 election rather than back him. But their anger at the president bubbled over at the Colorado summit.
