An offhand comment made by Fox News personality Brian Kilmeade about using “involuntary lethal injection” on mentally ill homeless people set off a wave of outrage on Saturday morning, and led to calls for him to be fired later that same day.

Conservative attorney and anti-Trump activist George Conway responded to Kilmeade's Fox segment, during which Kilmeade suggested that we "just kill them," saying, "I have no words for this."

But former prosecutor Elizabeth de la Vega wasn't at a loss for words. Responding to Conway, she said, "I have a few. Just fire him, @FoxNews. Now. Today."

In a separate post, the analyst wrote, "Let's not even hold back here. Brian Kilmeade should be fired. NOW."

Former presidential speechwriter Jon Lovett said, "I know we’re not easily shocked but I am surprised to see Kilmeade spitball about euthanizing homeless people."

"Other two on the couch don’t even seem fazed," he added. "Any other undesirables you’d add to the list, as long as we’re brainstorming?"

"This is a new low" for Fox News, declared ex-GOP lawmaker Adam Kinzinger in a Saturday video. "What has happened in this country?"

Kinzinger says if Fox News doesn't fire Kilmeade, the news outlet has no right to complain about anything anybody says.
