US Defense Secretary Lloyd Austin was hospitalized for a bladder issue and is expected to return to duties after non-surgical treatment.

Austin's hospitalization follows prostate cancer surgery in January and related complications.

The Pentagon has informed the White House and Congress of his condition, reflecting increased transparency after previous communication issues.

Austin's doctors anticipate a swift return to work, although the link between his current bladder issue and prostate surgery is unconfirmed.

Austin's absence coincides with key NATO defense talks in Brussels and a significant US Senate decision on a $95.34 billion aid package.

Deputy Defense Secretary Kathleen Hicks will perform Austin's duties in his absence, with Austin participating virtually in important meetings.

President Biden expresses confidence in Austin as he recovers, amidst ongoing global security challenges faced by the US.

Austin is set to testify before Congress on February 29 regarding the secrecy of his earlier hospitalization.
