But one of the women whose relationship with Finerty was scrutinized by the inspector general was Sen. Joni Ernst, according to two sources with knowledge of the investigation. The Iowa Republican and combat veteran is one of the most influential voices on the Hill about the military, and she sits on the Senate’s Armed Services Committee, which oversees the Pentagon and plays a crucial role in setting its annual budget.

Three other sources told ProPublica that around 2019 Ernst had a previous romantic relationship with a legislative affairs official for a different branch of the military, the Navy.
