In a note published by founder Arianna Huffinton on Monday, the website declared that Trump's campaign is no longer entertaining after he called for a "total and complete shutdown of Muslims entering the United States."
"Now that Trump, aided by the media, has doubled down on the cruelty and know-nothingness that defined his campaign's early days, the 'can you believe he said that?' novelty has curdled and congealed into something repellent and threatening — laying bare a disturbing aspect of American politics," Huffington explained.
The Huffington Post promised to continue presenting critical coverage of Trump, and accused those in the media who don't follow suit of legitimizing his bigotry and hateful views.
"As we've seen in the Republican race so far, Trump's worst comments don't occur in a vacuum — or land without repercussions," Huffington wrote. "They affect the tenor of the conversation, frequently moving the line between what's considered mainstream and what's considered unabashedly extreme and unacceptable.
"So we'll not only be covering the ways Trump's campaign is unique in recent American politics, but also the disastrous impact it continues to have on his fellow candidates — and the national conversation."
