Here's Charles Krauthammer's heartfelt message about his absence from Fox News

Fox News' conservative commentator Charles Krauthammer has been missing for weeks and he updated his condition for his supporters in a message delivered by anchor Bret Baier.

Here's what Krauthammer said

"Thanks to all for your cards, letters and good wishes," Krauthammer wrote. "I am still recovering from major surgery 12 weeks ago."

"I have graudated from the ICU to an advanced rehab facility to regain my strength and stamina," he continued. "It's a longer road than anticipated, but the support of family, friends and kindly viewers continue to sustain me."

"In the immortal words of Arnold Schwarzenegger, I'll be back," he concluded.

Are there any more details available?

Not really. Fox News has been very quiet about Krauthammer's condition, with just the leanest of details being allowed to trickle to the public. Bret Baier has occasionally updated the Fox News audience, but again, with few details.

Krauthammer was paralyzed from the neck down in 1971 in a swimming accident while studying at Harvard Medicine School.
