James Davis, a top aide to billionaire Charles Koch, left the Koch political network on Tuesday, underscoring a series of major changes for a force on the right that has pulled back from its heavy involvement in electoral politics.

Davis had worked at the Koch network for seven years, working in communications and strategy for the billionaire brothers as they were ridiculed by Democrats for their attempts to build Republican power in Washington and repeal Obamacare. He was a key aide at Freedom Partners and Freedom Partners Action Fund, the Koch-affiliated political nonprofit and super PAC that spent hundreds of millions of dollars supporting conservative causes and candidates.


Davis later helped the network revamp its firebrand image and refocus on policy and philanthropy, eventually rebranding under the name Stand Together.
