In a series of tweets not long before midnight on Monday, September 9th, President Donald Trump—sleepless and seemingly in a foul mood—targeted John Legend and Legend’s wife, Chrissy Teigen, for what Trump said was a failure to give him enough credit for supporting criminal justice reform.

Both Legend and Teigen responded to the attack with, basically, social media side-eye.

Addressing her young daughter with Legend, Teigen tweeted, “Luna, remember the night before your first day of school? When mommy was making your sign and the pussy ass bitch president had his 9th meltdown of the day.”

Trump’s ire was evidently triggered by a Sunday night special on MSNBC: A town hall about criminal justice, with NBC Nightly News anchor Lester Holt and featuring Legend. Beginning at 11:11 p.m., Trump, 73-years-old, went on the attack.

Teigen, 33-years-old—as comfortable on Twitter as Trump and a ninja with the clapbackresponded,

In another rejoinder to Trump, who labeled her “filthy mouthed,” Teigen told her followers, “No guys no please do not make this trend, for it is my fight with #PresidentPussyAssBitch, not yours!!!!!!”

“Your country needs you, Melania,” he added in another tweet, referring to First Lady Melania Trump.

Both Legend and Teigen have been outspoken critics of the president.

Earlier this year, Legend said Trump was a “flaming racist” for describing Baltimore as a “rodent infested mess” and in other inflammatory terms—apparently because a Baltimore lawmaker, Rep. Elijah Cummings, is one of Trump’s notable critics.

Teigen has had strong words for Trump too, tweeting in 2016 before he was elected: “He is truly, truly, a fucking monster.”

Criminal justice reform, the topic that ignited the latest in Trump’s long list of Twitter fights, has been one of the lone areas of bipartisanship in his administration, which has largely turned on more divisive issues such as blocking immigrants from the country.

Trump has found some celebrity allies with his criminal justice work, such as Wynonna Judd and Kim Kardashian West.
