Secretary of State Mike Pompeo is looking to resign from his post in the Trump administration so he can launch his senatorial campaign, but he’s unsure of how to leave unscathed by President Trump.

Pompeo, 55, originally planned on staying at the State Department until early spring, but that process might have been expedited, Time reported, citing three GOP sources. The sources included “one who served in the Trump Administration, another who remains in government, and a third who served in several high-ranking posts and is active in GOP politics.”
