Senator John Ensign (R-NV) “has stepped down from his leadership post one day after admitting he carried on a marital affair with a woman who was on his campaign staff,” the AP reports.
Ensign conveyed his decision in a phone call with Senate Republican Leader Mitch McConnell, who said he had accepted the resignation.
Ensign was chairman of the Republican Policy Committee, the fourth-ranking spot in the leadership.
He remained away from the Capitol during the day, and aides declined to answer additional questions about the affair.
