Former Fox News host Bill O'Reilly drew widespread criticism Friday after he said it is "inevitable" that President Donald Trump will be able to appoint a third justice to the Supreme Court.

O'Reilly's comments came after news broke that Supreme Court Justice Ruth Bader Ginsburg recently underwent surgery to remove cancerous cells from her lungs.

What did O'Reilly say?

"Justice Ginsburg is very ill. Another Justice appointment inevitable and soon. Bad news for the left," he tweeted.

Justice Ginsburg is very ill. Another Justice appointment inevitable and soon. Bad news for the left.

Presumably, O'Reilly believes that Ginsburg's health is ailing — indeed, she was hospitalized last month after falling in her office and breaking several ribs — to the point of necessary retirement, or worse, death. Ginsburg's departure from the court would allow Trump to nominate another justice to the Supreme Court.

What was the reaction?

Preemptively celebrating Ginsburg's departure from the Supreme Court amid another health scare did not go over well for O'Reilly.

There's really nothing more gross and ghoulish than people in the media pontificating on a public persons health and the hypothetical political ramifications of their death. Join me in praying for RBG to have a speedy and healthy recovery - we are Christians, aren't we Bill? https://t.co/03qXbBzEKQ

Wow @BillOReilly,this is sick. I am guessing you intended to wish her well and it just came out twisted. Did you really mean to make it sound like you are waiting for her to pass? https://t.co/LDHrT3K7RT

Others said:

"She outsurvived your career."

"Pig."

"Karma is looking directly at you."

"Apparently, you hit rock bottom and started to dig."

Meanwhile, Trump wished Ginsburg a speedy recovery.

"Wishing Supreme Court Justice Ruth Bader Ginsburg a full and speedy recovery!" he said on Twitter late Friday.
