On Wednesday, former U.S. president Jimmy Carter revealed he has advanced cancer. That prompted an outpouring of support by many -- and a nasty tweet by Fox News.

"Recent liver surgery revealed that I have cancer that now is in other parts of my body. I will be rearranging my schedule as necessary so I can undergo treatment by physicians at Emory Healthcare. A more complete public statement will be made when facts are known, possibly next week," Carter wrote in a statement posted to his foundation website.

A wide range of political and media personalities chimed in to wish Carter well.

But Fox News generated an angry backlash with a tweet attacking the 90 year old the day the announcement of his illness was made.

Conservative commentator Debbie Schlussel also had some ugly words about the news.

Schlussel even attempted to start the hashtag #ACancerHasCancer.

It is not trending.
