Companies are pulling their advertisements from Tucker Carlson's show on Fox News after he said mass immigration makes the U.S. "poorer and dirtier."

The big picture: This isn't the first time Fox News hosts have gotten heat for their rhetoric — Laura Ingraham faced similar pushback over tweets mocking Parkland school shooting survivor David Hogg earlier this year. Fox News stood by Ingraham then, and it continues to stand by Carlson now.

What they're saying

Carlson's comments on mass immigration:

"As an economic matter, this is insane. It's indefensible so nobody even tries to defend it. Instead, our leaders demand that we shut up and accept this. 'We have a moral obligation to admit the world's poor,' they tell us, even if it makes our own country poorer and dirtier and more divided. 'Immigration is a form of atonement; previous leaders of our country committed sins, we must pay for those sins by welcoming an endless chain of migrant caravans.' That's the argument they make."

Fox News statement:

"We cannot and will not allow voices like Tucker Carlson to be censored by agenda-driven intimidation efforts. ... Attempts were made last month to bully and terrorize Tucker and his family at their home. He is now once again being threatened via Twitter by far left activist groups with deeply political motives. While we do not advocate boycotts, these same groups never target other broadcasters and operate under a grossly hypocritical double standard given their intolerance to all opposing points of view.”

Advertisers pulling out:

Advertisers who have publicly said they're staying put:
