New York (CNN) More than a dozen companies have announced they will either pull or suspend their advertising from Tucker Carlson's Fox News show over comments about immigration he made last week.

Land Rover, IHOP, Ancestry.com, Just For Men, Minted , Smile Direct, Pacific Life , ScotteVest, Nerd Wallet, TD Ameritrade, Bowflex, CareerBuilder, Zenni and the Chase United MileagePlus Explorer card had as of Tuesday afternoon all released statements saying that they would no longer advertise on "Tucker Carlson Tonight."

The retreat from Carlson's program came as liberal activists and organizations pressured companies to abandon the show.

Carlson, a conservative who has made the subject of immigration a hallmark of his program, made the comments that led to the advertisers' decisions on Thursday night, when he said on his show that mass-immigration "makes our country poorer, and dirtier, and more divided."

After an initial backlash that included at least three advertisers pulling their commercials, Carlson defended those comments on his show Monday night, showing images of trash left at the US-Mexico border and arguing that "huge swaths of the region are covered with garbage and waste" left behind by immigrants "that degrade the soil and kill wildlife."
