In a series of since-deleted tweets, Ben Domenech called the late-night host an "untalented piece of s--t."
UPDATE 5/9/19 at 8:45 a.am: Seemingly in response to Domenech's comments, James Corden -- whose show airs at the same time as Seth's on another network -- showed praise to the fellow talk show host on social media.
"Just wanna take this moment to say that @sethmeyers is genuinely the kindest, sweetest, nicest man you could ever wish to meet," he tweeted. "Full of heart and compassion. Believe me, my job would be easier if he was a total asshole [Ed: something Domenech called him]. But my life is better that he isn't. He is one of the best."
McCain was a guest on "Late Night with Seth Meyers" last night, where the conversation got heated when he suggested it was "dangerous" for McCain to repeatedly bring up and condemn comments Rep. Ilhan Omar made that were considered anti-Semitic, after Omar had already apologized for them.
Omar was previously condemned by House leaders for making "deeply offensive" comments while criticizing the American Israel Public Affairs Committee's role in American politics. She later released a statement "unequivocally" apologizing.
On Meyers, McCain said she stood by "every single thing" she's said about Omar, adding, "If that makes me unpopular in this room or in front of you, so be it."
"Is there a way for people to talk about differences in Israeli policy without getting framed as anti-Semitic language?" Meyers asked, pushing back. He then also said he believes it's "unfair" of McCain to keep bringing up tweets for which Omar has already expressed regret.
"Are you her publicist? Are you her press person?" McCain asked in response. "What would make you happy coming out of my mouth right now, I'm genuinely curious?"
"I'm perfectly happy of everything that's come out of your mouth," he told her, "and I like that we spent this time together." When she then noted that her "opinions are very strong," Meyers quipped, "That is coming across, I do want you to know that!"
Following her appearance, McCain's husband and conservative commentaror Ben Domenech unloaded on social media in a series of since-deleted tweets.
"I see that @sethmeyers, the untalented piece of shit who only has his job because he regularly gargled Lorne Michaels' balls, went after my wife tonight with his idiotic anti-Semitic bullshit," he wrote.
"Seth is an awful person who is known within the industry for how terrible he is," he continued. "He is a monumental asshole who is utterly unfunny. He deserves the mockery he receives from all the people who laugh at him."
He added, "Here is proof that white men get ahead despite their obvious lack of talent: it's @sethmeyers, who would beg for a third of the viewers at @TheView. He's awful, untalented, and a perfect definition of a cuck."
While those tweets have since been removed, he followed them up with one apologizing for "rage tweeting" in the first place.
I love my wife. I apologize for rage tweeting about how Seth Meyers treated her. I don't like him, I think he's a hack, but I shouldn't have done that. I'm sorry to anyone I offended.
McCain hasn't addressed the appearance, except to thank conservative writer Seth Mandel for a pair of tweets calling her an ally and accusing Meyers of "protecting Congress's most prominent antisemite."
Late night hosts are deeply invested in protecting Congress's most prominent antisemite, and their normalization of Jew-hatred in this climate should be noted and not forgotten https://t.co/ujgFa7R5fg
