White House: Secretary Austin's doctors think he may need additional care

White House National Security spokesman John Kirby said on Sunday Defense Secretary Lloyd Austin's doctor's feel like he may still need some additional care.

"We'll see, you know, when he can be released, but obviously they still feel like he may need some additional care...part of that is just physical therapy," Kirby told CBS's 'Face the Nation.'

Austin remains hospitalized and is in good condition, the Pentagon said on Saturday, adding that it did not yet have a specific date for his release.
