Freshman GOP Sen. Ron Johnson (Wis.) is looking to purge nearly his entire Washington, D.C.-based legislative team, according to multiple Republican sources familiar with the situation.

Johnson’s frustration with his legislative staff has been one of the worst-kept secrets in Washington for months, those close to Republican Conference politics said.

But the situation in Johnson’s office has escalated in recent weeks. The top brass of the Senate Republican Steering Committee — the Conference’s conservative hub — have connected at least one Johnson legislative aide with another GOP Senate office, and sources indicated they may be helping others find jobs before they are asked to permanently clear their desks.

The executive director for the committee declined to comment on this story.

The Wisconsin Senator said recently that he would like to refocus his efforts on political messaging, and Minority Leader Mitch McConnell (Ky.) has asked him to help coordinate strategy with the eventual GOP presidential nominee.
