Fox News host Tucker Carlson missed his Thursday night show after he went to the hospital with appendicitis.

Ed Henry took over the 8pm show, which went ahead and aired Carlson's interview with Frank Warmbier, father of the released North Korean detainee Otto Warmbier.

CNN anchor Jake Tapper wished Tucker a speedy recovery on Twitter, but his followers did not share in his sympathy, with one man writing: 'If I were an internal organ I'd want to get the F out of Tucker too.'

Carlson's pre-taped interview with Frank Warmbier, father of the released North Korean detainee Otto Warmbier, went ahead and aired on Thursday night

On Friday morning, Tapper wished Carlson a 'speedy recovery' - even though Twitter users did not share in his good will

Carlson had a fever, and his doctor urged him to go to the hospital, where he was diagnosed with appendicitis, Mediaite reported.

The condition, which can lead to death if not treated in time, usually requires the inflamed appendix to be surgically removed.

A Fox News spokesperson confirmed the medical emergency and said: 'Tucker is now being treated for appendicitis. He is in good spirits and expects to back on the air soon.' Dana Perino will take over for Tucker on Friday night.

On Friday morning, Tapper tweeted: 'Get well soon to @TuckerCarlson -- hoping for a speedy recovery!'

While some Twitter users credited Tapper for being 'classy', others were happy to use it as an opportunity to knock the FOX News host.

Not everyone was sympathetic. But the response then faced a backlash from people like Alana Mastrangelo, who called liberals 'appalling'

User @suzg2017 wrote, 'All that regurgitating venom finally needed a way out' while Myra Parker tweeted: 'Hope he has better insurance than the @GOP is offering us.'

Steve Minard chimed in, asking: 'So he's finally having his head surgically removed from his a**?'

User @D_Anthony36 wrote: 'Was hoping he was getting vocal chords removed. Oh well. Hope he gets better soon and takes a long time resting before returning.'

User @a662 pushed back at the response and wrote: 'It's disappointing how quick people are to take feckless jabs when Jake Tapper here is just trying to be genuinely nice and wish him well.'

Alana Mastrangelo, on the other hand, lashed out at liberals, writing: 'Tucker Carlson is in the hospital for appendicitis, and as usual, liberals jump at the opportunity to display how appalling they are.'

Carlson's pre-taped interview with Fred Warmbier aired on Thursday even though the host was in the hospital. The father called North Korea a 'pariah regime'

Warmbier was sentenced to 15 years of hard labor for stealing a poster during a visit to the hermit state. He was released this week, although doctors said much of his brain has died

Carlson's pre-taped interview with Fred Warmbier aired on Thursday even though the host was in the hospital.

In it, Warmbier said: 'They're brutal. There's no sense to anything here. They've crossed a line with my son, Otto.'

He added: 'Otto was terrorized and brutalized for 18 months by a pariah regime in North Korea.

'We are thrilled to have him home. He’s with his family. His mom is with him right now, and I’ll be with him later today.'

At a Thursday afternoon press conference, doctors at the University of Cincinnati Medical Center revealed that much of the 22-year-old's brain has died, leaving him without the ability to speak, understand language or even move - besides the occasional fluttering of his eyelids.

The doctors appeared to refute the North Korean regime's account that Warmbier went into a coma after getting botulism a day after he was sentenced to 15 years of hard labor for stealing a poster during a visit to the hermit state.
