This story surrounding the secrecy of Biden’s Secretary of Defense being hospitalized is getting more bizarre.

It turns that even Deputy Defense Secretary Kathleen Hicks, who was on vacation in Puerto Rico, did not know that Austin was in the hospital when she was asked to take over his duties.

This is according to two defense officials via CNN:

When the deputy secretary of defense began assuming some of Secretary of Defense Lloyd Austin’s responsibilities on January 2, not even she knew that it was because Austin was hospitalized, two defense officials told CNN.

Deputy Secretary of Defense Kathleen Hicks, the Pentagon’s number two leader, was among the senior leaders kept in the dark about Austin’s true whereabouts until Thursday, three days after the secretary checked into Walter Reed medical center following complications from an elective surgery. Not even the president was aware of Austin’s hospitalization until three days into his stay there, CNN previously reported.

The revelation that not even Hicks knew that Austin was hospitalized is sure to add to questions swirling within the administration about why his status was kept secret, not only from the public but from senior national security officials and the White House.

Secretary of State Antony Blinken said Sunday he had not been aware that Austin had been hospitalized. The two spoke the weekend before Austin was hospitalized on New Year’s Day, Blinken said at a news conference in Qatar, but he declined to engage in “hypotheticals” when asked what his own notification policy would be if he were hospitalized. Blinken called Austin an “extraordinary leader” and wished him a full recovery.

Pentagon Press Secretary Maj. Gen. Pat Ryder told CNN on Sunday that Austin transferred “certain operational responsibilities that require constant secure communications capabilities” to Hicks on January 2, the day after he was admitted to Walter Reed. Throughout last week, Hicks made “some routine operational and management decisions” for the Pentagon and was authorized to support the president.

But Hicks, who was on vacation in Puerto Rico at the time, was not informed of Austin’s hospitalization until the afternoon of January 4, the defense officials said. Ryder told CNN that it is “not uncommon” for the secretary to transfer certain responsibilities without providing a specific reason as to why such a transfer is needed.

At that point, Hicks began to make contingency plans to return to Washington, DC, on Friday, the official said. But because Austin was expected to return to his full duties—albeit from the hospital—on Friday, she decided to stay in Puerto Rico to ensure continuity of communications.

“There are all of these people around the secretary at all times, who manage him and help him on a day-to-day basis, and no one had the wherewithal to even tell the White House?” said one Pentagon official. “I’m surprised no one is using the word ‘cover-up’ yet.”
