“Austin was admitted to Walter Reed National Military Medical Center for complications following a recent elective medical procedure,” Pentagon press secretary Maj. Gen. Pat Ryder said in the statement.

“At all times, the Deputy Secretary of Defense was prepared to act for and exercise the powers of the Secretary, if required.”

The Pentagon did not specify what type of surgery Austin had or when he would be discharged.

Deputy Secretary of Defense Kathleen Hicks was sworn into the role in 2021 and is currently the highest-ranking woman in the Defense Department.

“Of note, the secretary did not have to affirmatively delegate his duties because by statute, the deputy secretary is automatically authorized to perform the duties of the secretary if he is unable to perform them,” Ryder told the Washington Post.

The delayed news from the Pentagon about Austin’s health drew criticism from some circles.

The Pentagon Press Association wrote in an open letter to Ryder and Assistant to the Secretary of Defense for Public Affairs Chris Meagher complaining about the situation.

“The public has a right to know when U.S. Cabinet members are hospitalized, under anesthesia or when duties are delegated as the result of any medical procedure,” the press group said. “That has been the practice even up to the president’s level. As the nation’s top defense leader, Secretary Austin has no claim to privacy in this situation.”

The group requested a meeting with the Pentagon officials “to discuss this troubling situation as soon as possible.”

Austin is a retired four-star U.S. Army General and the first Black man to hold the title of Secretary of Defense.

Acting Under Secretary of Defense for Policy Sasha Baker is third in line to lead the Defense Department should both Austin and Hicks become unavailable to perform their duties.
