U.S. Defense Secretary Lloyd Austin on Tuesday made his first public appearance, virtually and from home, since his secret hospitalization, during a meeting on Ukraine’s military needs.

He skipped over prepared remarks that would have addressed his health.

Austin, 70, was admitted to Walter Reed National Military Medical Center in Maryland on December 22 to treat prostate cancer. He returned to the hospital on January 1 due to complications, including a urinary tract infection. His hospitalization was not revealed until four days later, and the Pentagon did not specify why he was being treated until January 9.

Austin’s failure to tell President Joe Biden he was hospitalized drew criticism from lawmakers and caught the White House by surprise.

Austin appeared on the livestream for a few minutes as he made his opening remarks. He was sitting in front of a white wall with what appeared to be a security system keypad on his left and a Department of Defense seal on the right, with small U.S. and Ukrainian flags on top of a printer next to it.

While there was a slight break in the livestream, Austin did not address his health, even though the topic was in his prepared remarks.

He is not expected to take part in a joint press conference with the top U.S. general after the meeting, something that has become routine after such gatherings.
