WASHINGTON • Christine Wormuth was confirmed unanimously by the Senate on Thursday to be the first female secretary of the Army.

Wormuth, who led President Joe Biden’s transition team at the Pentagon, got an overwhelmingly warm reception from members of the Senate Armed Services Committee during a hearing this month. Her confirmation sets her up as one of the more powerful officials in a defense establishment long dominated by men. She is the second woman named to a top Pentagon role by Biden. The deputy secretary of defense is Kathleen Hicks.

During her hearing, many of the senators pressed Wormuth on a range of personnel issues that have plagued the Army, ranging from sexual assault and racial tensions, to strains on a force that has been in combat for the past two decades.

The Army’s handling of sexual assaults and other violence has come under significant scrutiny in the aftermath of a series of crimes, including murders and suicides last year at Fort Hood, Texas. A review panel found leaders at the post were not adequately dealing with high rates of sexual assault and harassment and were neglecting the sex assault prevention program.

Wormuth told the committee that she was “angry and frustrated” by the failures at Fort Hood. And she said the Army needs to “put quite a bit of focus” on improving the command climate all the way down to the lower levels so that younger soldiers feel safe and are able to make complaints if needed.
