Iowa Sen. Joni Ernst is an Iraq War veteran and sexual assault survivor who has advocated for years to improve how the military handles claims of sexual misconduct. But she now finds herself in the position of seriously considering Pete Hegseth to serve as defense secretary. Hegseth once said women should not serve in combat and has been accused of sexual assault. The Republican senator is facing an aggressive pressure campaign from President-elect Donald Trump’s allies, complete with threats of primary challengers. It serves a warning to Ernst's colleagues who may have qualms about Trump’s other controversial picks for his Cabinet.
